Knowledge of African Traditional Medicine System: Immunomodulation

African traditional medicine is one of the oldest forms of health-care system in the continent that has continued to be relevant. It is usually holistic, treating mind and body, and includes aromatherapy, bone setting, circumcision, herbs, homeopathy massaging, spiritual therapies, maternity care, psychiatric care, music therapy, and many more. It is a very old and culturally informed method of health management that humans have used against diseases that have threatened existence. More than 60,000 of the world's higher plant species can be found in sub-Saharan Africa and the Indian Ocean Islands. These are about one-fourth of the global total and less than the 8% of the medicinal plants sold internationally from Africa. This scarcity could be due to lack of data on the traditional uses of many African plants as the knowledge is transferred orally by storytellers and traditional healers though in recent times, there are some information in print. Immunomodulation is seen as an essential feature of immunotherapy whereby immune responses are provoked, heightened, decreased, or avoided. Immune responses have been observed to be either cellular co-receptor expression, class switching, cytokine secretion, histamine release, immunoglobulin secretion, lymphocyte expression, or phagocytosis. Immune system dysfunction is responsible for various diseases like allergies, asthmas, arthritis, cancers, and infectious diseases. So modulation of immune responses is required in controlling diseases. This is requisite nowadays because of the upsurge of infectious diseases like superbugs caused by Multi-Resistant Staphylococcus aureus (MRSA) and the coronavirus (COVID-19) plus other emerging diseases. The historical view of African Traditional Medicine (ATMs) will be discussed from the point of view of specific plants used for immunomodulation in the ATMs and their efficacies following the trend of use and development of herbal medicines from crude formulations to refined dosage forms and procedures over time. Most of the ATMs are prepared as tonics and bitters to heighten and keep up immune defenses. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.

Potential inhibition of Melaleuca leucadendron L. compounds against the NSP5 SARS CoV-2 protein

COVID-19 is an infectious disease caused by Severe Acute Respiratory Syndrome (SARS-CoV-2), causing a global health emergency as a pandemic disease. The lack of certain drug molecules or treatment strategies to fight this disease makes it worse. Therefore, effective drug molecules are needed to fight COVID-19. Non Structural Protein (NSP5) or called Main Protease (Mpro) of SARS CoV 2, a key component of this viral replication, is considered a key target for anti-COVID-19 drug development. The purpose of this study is to determine whether the compounds in the Melaleuca leucadendron L. plant such as 1,8-cineole, terpene, guaiol, linalol, a-selinenol, beta-eudesmol and P-eudesmol are predicted to have antiviral activity for COVID-19. Interaction of compounds with NSP5 with PDB code 6WNP analyzed using molecular docking with Molegro Virtual Docker. Based on binding affinity, the highest potential as an anti-viral is Terpineol with binding energy (-119.743 kcal/mol). The results of the interaction showed that terpinol has similarities in all three amino acid residues namely Cys 145, Gly 143, and Glu 166 with remdesivir and native ligand. Melaleuca leucadendron L. may represent a potential herbal treatment to act as: COVID-19 NSP5, however these findings must be validated in vitro and in vivo.

ANTIVIRAL HERBS.

Objective: Viruses are agents that can infect all kinds of living organisms, and the most important hosts are humans, animals, plants, bacteria and fungi. Viral diseases are responsible for serious morbidity and mortality worldwide, are a major threat to public health, and remain a major problem worldwide. The recently prominent Coronaviruses (CoVs) within this group belong to the Coronaviridae family, subfamily Coronavirinae, and are large (genome size 26-32 kb), enveloped, single-stranded ribonucleic acid (RNA ) viruses that can infect both animals and humans. The world has experienced three epidemics caused by betaCoVs in the last two decades: SARS in 2002-03, MERS in 2012, and COVID-19, first identified in 2019. COVID-19 continues to be our current health problem and studies on the subject continue. Result and Discussion: The term "antiviral agents" is defined in very broad terms as substances other than virus-containing vaccine or specific antibody that can produce a protective or therapeutic effect for the clearly detectable effect of the infected host. Nature has the potential to cure humanity's helplessness against viruses with many different plant species with strong antiviral effects. During the screening of plants with antiviral effects, focusing on plants used in folk medicine is of great importance in terms of maximizing the benefit to humanity - saving time and effort by dealing with valuable ancient knowledge on a scientific basis. In this review, viral diseases and the plants used in these diseases and determined to be effective are mentioned.Copyright © 2022 University of Ankara. All rights reserved.

Potential cultivating plant-based raw materials in Mecklenburg-Vorpommern for the pharmaceutical industry: an online survey from the perspective of the pharmaceutical industry

The goal of this study is to assess the potential of cultivating plant-based raw materials in Mecklenburg-Vorpommern from the perspective of the pharmaceutical industry and to discuss the factors that could hinder the realization of high-quality cultivation. Procuring high-quality plant-based materials is crucial for the production of plant-based medicines, and the pharmaceutical industry has faced increasing challenges in sourcing these materials in recent years. The methodology involved surveying pharmaceutical companies that are members of the German Pharmaceutical Industry Association and are involved in the fields of homeopathic/anthroposophic medicines and plant-based pharmaceuticals. An online questionnaire was used to collect data. According to the pharmaceutical industry's perspective, there is growing demand for plant-based raw materials from domestic cultivation. Stable supply chains, quality, and reliability are seen as primary advantages over foreign cultivation. Geopolitical conflicts, climate change, and the COVID-19 pandemic have negatively affected the stability of supply chains for imported goods. 73% of companies reported encountering import difficulties multiple times. The majority of pharmaceutical companies can envision increased cooperation with agricultural enterprises in Mecklenburg-Vorpommern. Sustainability in sourcing was already deemed significant by more than two-thirds of the respondents. The study concludes that the importance of sustainable pharmaceutical production, stable supply chains, and high-quality plant-based raw materials will continue to grow. Mecklenburg-Vorpommern provides favorable conditions to meet a portion of the demand. To fully utilize the theoretical potential, close collaboration between the industry, academia, and policymakers is needed, along with minimizing regulatory and bureaucratic barriers for agricultural enterprises.

Pharmacological Properties and Safe Use of 12 Medicinal Plant Species and Their Bioactive Compounds Affecting the Immune System

This paper presents raw plant materials and their characteristic compounds which may affect the immune system. Plant-derived agents in specific doses affect the body's non-specific, antigen-independent defense system. They have immunostimulatory effects on the entire immune regulatory system. They can enhance the immune response through various factors such as macrophages, leukocytes, and granulocytes, as well as through mediators released by the cellular immune system. This paper was inspired by the threats caused by the COVID-19 pandemic. The proper functioning of the immune system is important in limiting the effects of viral infection and restoring the normal functioning of the body. This paper also emphasizes the importance of the skillful use of plant immunostimulants by potential patients, but also by those who prescribe drugs. It is important not only to choose the right plant drug but above all to choose the correct dose and duration of treatment.

Herbal remedies in post-COVID trauma: a systematic review

The world has faced huge challenges throughout the endemic of COVID-19. The survivors of Covid too are facing health difficulties. The non-availability of specific treatments made researchers search for all the possible treatment regimens including traditional medicines. India has the greatest culture of Ayurveda. Indian government's AYUSH ministry has granted permission for use of ancient systems of medicine for treatment of some of the COVID-19 cases, especially which are not at advanced stages. Along with this certain reports are there which have shown the positive outcomes of Ayurvedic treatment of COVID-19. However, it is more beneficial to build the immune system of the host from a large population and its health perspective to avoid widespread infection and control the potency of the infectious viral particles. A vaccine can offer protection by boosting specific immunity in the host at the same time non-specific ways to improve host immunity are suggestible. This has carved a path for the use of ancient Indian therapeutic methods such as Ayurveda and Yoga. Although there are many general articles where the home remedies have suggested but, more scientific references are required to document the ayurvedic medicines for Covid related ailments. In this review, an attempt is made to organize available evidences of usefulness of Ayurveda, Yoga, in COVID-19.

The birth of Boererate: women and healing during the South African war

This article reinterprets historical works on the history of medicine in South Africa and how present-day Afrikaner home-based healing therapies known as Boererate engage with this history. By reinterpreting historical sources, we illustrate how Boer women in concentration camps during the South African War were waging an ideological war. We argue that there is a distinction between the creolised medicines that Boer women took into the concentration camps and the body of knowledge — Boererate — that emerged from the camps after the women were released. The article brings archival research and interviews with interlocutors into conversation to show how a knowledge system like Boererate has persisted through time and become very popular in online forums and Facebook groups during the Covid-19 pandemic. The article is part of a wider project investigating Boererate in historical and diverse contemporary contexts. (English) [ FROM AUTHOR] Este artigo reinterpreta estudos históricos sobre a história dos medicamentos na África do Sul e como as atuais terapias caseiras africâneres conhecidas como Boererate se relacionam com essa história.

Safety and Efficacy of Popular Iranian Herbal Cold Remedy for COVID-19: A Randomized Clinical Trial in Mild to Moderate COVID-19 Cases

Background: In traditional Persian medicine, an herbal cold remedy containing Sugarcane, Black Myrobalan, and mastic is mentioned and it was being widely provided by grocery stores. With the advent of the COVID-19 pandemic, the increased desire for this traditional remedy has led to a debate in society. Huge parts of the Iranian population have started using this remedy for the treatment of COVID-19;while no study has evaluated its efficiency and possible side effects. Thus, we aimed to evaluate the effects of Sugarcane, Black Myrobalan, and Mastic herbal medications for COVID-19 patients. Methods: This was a double-blinded randomized clinical trial study conducted over three months from May 2020 to July 2020 in SARS-COV2 PCR positive patients admitted in the COVID-19 ward of Peymaniyeh Hospital in Jahrom, Iran. Patients with severe COVID-19 infection were not recruited. The intervention group received the routine COVID-19 treatment protocol and the herbal supplement received the combination of black myrobalan and mastic and sugarcane, twice a day (3 g of herbal supplement). Study groups were compared in terms of demographic variables, vital signs, and clinical and laboratory variables for safety and efficiency assessment. Results: Seventy-two patients with COVID-19, divided into intervention (n=37) and control (n = 35) groups were studied. Intervention and control groups had not any significant difference in terms of baseline characteristics. The time-to-event analysis revealed a statistically significant difference in 4 symptoms of cough, fever, dyspnea, and myalgia (P<0.05). There was no significant difference in averaged O2 vital signs between the two groups (P>0.05). The Control group in comparison to the intervention group had a significantly lower decrease in C-reactive protein during 7 days (P<0.05). Patients in the herbal supplement group were hospitalized for 4.12 days and patients in the control group were hospitalized for 8.37 days (P=0.001). ICU admission and death only happened in 3 (8.6%) patients of the control group. Conclusion: This study showed that the proposed herbal remedy could be applied as supplementation to conventional management of COVID-19 patients with mild disease, while more research is needed for clinical application of this remedy. © 2023 by SPC (Sami Publishing Company)

Herbal medicine use in Republic of Korea to alleviate side effects of COVID-19 vaccines: A cross-sectional study.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has spread worldwide, and several virus variants have emerged. Vaccines are administered to help prevent the infection. In Republic of Korea, most people take herbal medicine. This study investigated the use of herbal medicine to counter the side effects of COVID-19 vaccines. METHODS: This cross-sectional study was conducted using an online survey. Chi-square tests were used to determine differences in the use of herbal medication according to sociodemographic characteristics. Independent two-sample and paired t-tests were performed to examine the effect and satisfaction of herbal medicine use for countering the side effects of COVID-19 vaccines. One-way analysis of variance was used to determine vaccine-related differences. RESULTS: A total of 233 and 181 participants received the first and second doses of COVID-19 vaccines, respectively. The majority of herbal medicine users were in their thirties, had a bachelor's degree, suffered from side effects of vaccination, and received Vaxzevria for their first COVID-19 vaccine dose and Comirnaty for their second dose. The herbal medicine group had a higher satisfaction level of post-vaccination side effects than the non-herbal medicine group (P < 0.0001). The numeric rating scale scores for vaccination side effects were lower among participants who took herbal medication to alleviate those symptoms (P < 0.0001). The most commonly used herbal formula was Shuanghetang. CONCLUSION: A third of participants receiving COVID-19 vaccines used herbal medication to counter the side effects of vaccination. The use of herbal medicine was associated with age, education level, vaccine brand, and whether side effects of vaccination occurred. Herbal medication use was associated with greater satisfaction compared to vaccine recipients not using herbal medication. Please cite this article as: Yoon HC.

Perspectives of international multi-center clinical trials on traditional Chinese herbal medicine.

With the introduction of various subjects, such as clinical epidemiology and evidence-based medicine, the qualities and levels of Traditional Chinese Herbal Medicine (TCHM) in China improved substantially, and the processes of internationalization of Traditional Chinese Medicine (TCM) are further accelerated. Since, a variety of drug products in China have been approved for marketing in other countries, and approximately 10 products have submitted the IND application to FDA of United States, of which various Chinese herbal preparations such as compound Danshen dripping pills, Xingling granules, and HMPL-004 have been approved to be investigated in phase III clinical trials. In general, multi-center studies of TCHM are increasing with years, but most of the studies are performed in some certain country, and the actual international multi-center clinical trials are very rare. Number of SCI literatures on multi-center clinical trials of TCHM that published in the recent decade also showed increasing tendency with years, despite the evident reduction in the past 2 years due to the influence of COVID-19 pandemic. Of the multi-center clinical trials of TCHM that performed by mainland China and other oversees regions, except for Taiwan, China, nearly 70% were focused on classic Chinese medicinal formulae and Chinese patent medicine, while the other 30% were on dietary supplements and plant extracts. Facing the future, the "human experience" has attracted close attentions from researchers throughout the world. Effectively utilizing the historic "human experience" is an important method to vitalize potential of original scientific and technological resources of TCHM. Performing multi-center clinical trials with high qualities is still an essential method for TCHM in accessing the mainstream medicine market. In addition, it is also required to further improve the evaluation techniques and methods that not only meet the international standards but also meet the characteristics of TCHM. Furthermore, we should also focus on the TCHM specific clinical values and scientific reports.

Promising roles of Zingiber officinale roscoe, Curcuma longa L., and Momordica charantia L. as immunity modulators against COVID-19: A bibliometric analysis.

Zingiber officinale, Curcuma longa, and Momordica charantia are medicinal plants that are commonly used in the form of herbal tea, which is formulated to strengthen the immune system, especially against COVID-19 infection. Excellent antioxidant, anti-inflammatory, and immunostimulatory properties have been reported for their bioactive compounds, which have been shown to aid in stimulating immune systems as well as lowering the risk of severe COVID-19 such as lung injury. Yet, no bibliometric study on the subject is available. Hence, the purpose of this study is to quantitatively examine the existing articles related to the therapeutic potential of these three herbs, as well as their mechanisms of action in combating the SARS-CoV-2 virus. A total of 121 papers were retrieved from Scopus database up to 14th March 2023. The bibliometric analysis was conducted using VOSviewer software. Based on the literature search, Z. officinale was the most researched plant. India appeared as the most prolific country, with the highest number of articles contributed by two authors from India (Rathi, R. and Gayatri Devi, R.). In terms of keywords, the plants were associated with immune modulation, management of symptoms, antioxidant, anti-inflammatory and antiviral activities. Several important bioactive compounds were responsible for these effects such as gingerol, paradol, shogaol, curcumin, calebin A, momordicoside, karaviloside and cucurbitadienol. These compounds were hypothesized to prevent and cure COVID-19 by regulating inflammatory response, downregulating oxidative stress and modulating immunostimulatory activity. This review paper therefore supports the potential of Z. officinale, C. longa, and M. charantia to be formulated as a herbal blend for treating and preventing COVID-19 infection.

Deciphering suppressive effects of Lianhua Qingwen Capsule on COVID-19 and synergistic effects of its major botanical drug pairs.

The COVID-19 pandemic has resulted in excess deaths worldwide. Conventional antiviral medicines have been used to relieve the symptoms, with limited therapeutic effect. In contrast, Lianhua Qingwen Capsule is reported to exert remarkable anti-COVID-19 effect. The current review aims to: 1) uncover the main pharmacological actions of Lianhua Qingwen Capsule for managing COVID-19; 2) verify the bioactive ingredients and pharmacological actions of Lianhua Qingwen Capsule by network analysis; 3) investigate the compatibility effect of major botanical drug pairs in Lianhua Qingwen Capsule; and 4) clarify the clinical evidence and safety of the combined therapy of Lianhua Qingwen Capsule and conventional drugs. Numerous bioactive ingredients in Lianhu Qingwen, such as quercetin, naringenin, ß-sitosterol, luteolin, and stigmasterol, were identified to target host cytokines, and to regulate the immune defence in response to COVID-19. Genes including androgen receptor (AR), myeloperoxidase (MPO), epidermal growth factor receptor (EGFR), insulin (INS), and aryl hydrocarbon receptor (AHR) were found to be significantly involved in the pharmacological actions of Lianhua Qingwen Capsule against COVID-19. Four botanical drug pairs in Lianhua Qingwen Capsule were shown to have synergistic effect for the treatment of COVID-19. Clinical studies demonstrated the medicinal effect of the combined use of Lianhua Qingwen Capsule and conventional drugs against COVID-19. In conclusion, the four main pharmacological mechanisms of Lianhua Qingwen Capsule for managing COVID-19 are revealed. Therapeutic effect has been noted against COVID-19 in Lianhua Qingwen Capsule.

"The History of Chinese Medicine Really Is Very Detailed Regarding Pandemics": A Qualitative Analysis of Evidence-Based Practice and the Use of Chinese Herbal Medicine by Licensed Acupuncturists During the COVID-19 Pandemic in the United States.

Objective: The objective of this qualitative study was to understand how licensed acupuncturists determined treatment strategies for patients with symptoms likely related to COVID-19 using Chinese herbal medicine (CHM) and the impact of the pandemic upon their clinical practice. Methods: A qualitative instrument was developed with questions aligned with when participants started treating patients with symptoms likely related to COVID-19 and the availability of information related to the use of CHM for COVID-19. Interviews took place between March 8 and May 28, 2021, and were transcribed verbatim by a professional transcription service. Inductive theme analysis and ATLAS.ti Web software were used to determine themes. Results: Theme saturation was achieved after 14 interviews lasting 11-42 min. Treatment predominantly started before mid-March 2020. Four themes emerged (1) information sources; (2) diagnostic and treatment decision-making; (3) practitioner experience; (4) resources and supplies. Conclusion: Primary sources of information informing treatment strategies came from China through professional networks and were widely disseminated throughout the United States. Scientific studies evaluating the effectiveness of CHM for COVID-19 were generally not deemed useful for informing patient care because treatment had been initiated before they were published and because of limitations associated with the research and the ability to apply it to real world practice.

Investigation of the inhibitory activity of extracts, fractions and secondary metabolites of Silene spp. (Caryophyllaceae) and Serratula cupuliformis (Asteraceae) on the replication of SARS-CoV-2 coronavirus

Aim. In vitro analysis of the inhibitory activity of extracts, fractions and secondary metabolites of plants of the genus Silene (Caryophylaceae) and Serratula cupuliformis (Asteraceae) on the replication of SARS-CoV-2.Material and Methods. Silene spp. and Serratula cupuliformis of the Siberian Botanical Garden of National Research Tomsk State University were used. Ethanol extracts and butanol fractions of Silene spp. were prepared. The flavonoid shaftoside and the ecdysteroid 20hydroxyecdysone from Lychnis chalcedonica were isolated. Analysis of BAS was carried out by the HPLC method. In vitro analysis of the inhibitory activity of extracts on SARS-CoV-2 replication was performed in Vero cell culture by direct inactivation (neutralization) of virions. Comparison samples were dry ethanol extracts of chaga (Inonotus obliquus, Basidiomycota), spices of cloves (Syzygium aromaticum, Myrtaceae) and root of licorice (Glycyrrhiza glabra L., Fabaceae).Results. The inhibitory activity of ethanol extracts and butanol fractions of Silene spp., as well as individual compounds (shaftozide and 20-E) was revealed in the range of 50% effective concentrations (EC50) when dissolved in water from 339.85 +/- 83.92 mu g/ml to 1.59 +/- 0.39 mu g/ml and when dissolved in DMSO from 119.34 +/- 26.34 mu g/ml to 2.22 +/- 0.57 mu g/ml, respectively. The butanol fraction of Serratula cupuliformis was active with EC50=21.74 +/- 4.80 and 27.42 +/- 6.05 mu g/mL. These results for some samples of Silene spp. and Serratula cupuliformis are comparable to the EC50 values of the comparators.Conclusion. The results obtained suggest the presence of biologically active substances in the herbal preparations studied that act destructively on virions of SARS-CoV-2 and affect one of the main stages of its "life" cycle - on the attachment to receptors of sensitive cells.

In-silico screening of plant-derived natural compounds for their anti-COVID-19 potential

The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in Wuhan, China, in December 2019 and quickly spread across the worldwide. It becomes a global pandemic and risk to the healthcare system of almost every nation around the world. In this study thirty natural compounds of 19 Indian herbal plants were used to analyze their binding with eight proteins associated with COVID -19. Based on the molecular docking as well as ADMET analysis, isovitexin, glycyrrhizin, sitosterol, and piperine were identified as potential herbal medicine candidates. On comparing the binding affinity with Ivermectin, we have found that the inhibition potentials of the Trigonella foenum-graecum (fenugreek), Glycyrrhiza glabra (licorice), Tinospora cordifolia (giloy) and Piper nigrum (black pepper) are very promising with no side-effects.

Knowledge and attitudes towards herbal and dietary products use during the COVID-19 pandemic.

Background and aim: The outbreak of coronavirus (COVID-19) has made a global public health disaster. Little information is known about how to combat this infection. Therefore, preventive health measures that can reduce the severity and progression of this disease are needed. Some dietary supplements and herbal products have antiviral and anti-inflammatory effects. Thus, it may be used to enhance immunity and reduce the risk of COVID-19 infection. In this study, we reviewed selected supplements that may play a key role in the prevention and management of COVID-19 (e.g. vitamin D, vitamin C, and zinc), and that was to determine the level of knowledge and attitudes toward them by the adult population in Jordan. Methodology: This is a cross-sectional study design, in which an online questionnaire was conducted and distributed on different social media websites. People who are above 18 years old were included in this study. Demographic, Attitudes, and knowledge data were collected and then analyzed using the Statistical Package for Social Sciences (SPSS 23). Results: In this study, (62.8%) of participants became more concerned with their health during the COVID-19 pandemic, and (49.2%) of them used dietary and herbal supplements to protect themselves from the coronavirus. In addition, (18.5%) of participants reported that they had used these supplements for a while and then stopped. Conclusion: The findings of our study provided evidence that the general population in Jordan has a reasonable level of knowledge and acceptance of dietary and herbal supplements used during the COVID-19 pandemic.

Fostering home-grown response to COVID-19: development of improved traditional herbal medicines to WHO standards

Facing the unprecedented burden and rapid spread of the Covid-19 pandemic across the globe, responses from various regions have been exceptionally quick. Drug discovery has been essentially based on repurposing, particularly at the onset of the scourge. Several experimental models have been designed ranging from in vitro cell culture systems to nonhuman primates;however, each with advantages and limitations. It was revealed beside its detrimental consequences on health, economy and the society, Covid-19 has also provided opportunity to highlight the immense potential of traditional medicine as a valid alternative for addressing major health threat. The African traditional medicine has been instrumental for the control of the COVID-19 pandemic in the continent, in situation of extremely low vaccination coverage. For optimal and sustainable use of traditional medicine, we strongly recommend products be developed following the WHO standards, while taking into consideration sustainability, environmental protection and copyright issues surrounding the natural product-based drug research and development.

Influence of biochar on improving hydrological and nutrient status of two decomposed soils for yield of medicinal plant - Pinellia ternata

The root tuber of Pinellia ternata has been used as a traditional therapeutic herbal medicine. It is reported to impart beneficial attributes in recovering COVID-19 patients. To meet an increasing demand of P. ternata, this study is intended to investigate the effects of biochar on the soil hydrological and agronomic properties of two decomposed soils (i.e., completely decomposed granite (CDG) and lateritic soil) for the growth of P. ternata. The plant was grown in instrumented pots with different biochar application rate (0%, 3% and 5%) for a period of three months. Peanut shell biochar inclusion in both soils resulted in reduction of soil hydraulic conductivity and increase in soil water retention capacity. These alterations in hydrological properties were attributed to measured change in total porosity, biochar intra pore and hydrophilic functional groups. The macro-nutrient (i.e., N, P, K, Ca, and Mg) concentration of both soils increased substantially, while the pH and cation exchange capacity levels in the amended soils were altered to facilitate optimum growth of P. ternata. The tuber biomass in biochar amended CDG at all amendment rate increases by up to 70%. In case of lateritic soil, the tuber biomass increased by 23% at only 5% biochar application rate. All treatments satisfied the minimum succinic acid concentration required as per pharmacopoeia standard index. The lower tuber biomass exhibits a higher succinic acid concentration regardless of the soil type used to grow P. ternata. The biochar improved the yield and quality of P. ternata in both soils.
