ABSTRACT
BACKGROUND: The pecan nutshell contains phytochemicals with various biological activities that are potentially useful in the prevention or treatment of diseases, such as cancer, diabetes, and metabolic imbalances associated with heart diseases. OBJECTIVE: The aim of this study is to update this topic by means of a literature review and include those studies that contribute to the knowledge of the chemical composition and biological activities of pecan nutshell, particularly those related to the therapeutic potential against some chronic degenerative diseases associated with oxidative stress. METHODS: Exhaustive and detailed review of the existing literature was conducted using electronic databases. CONCLUSION: The pecan nutshell is a promising natural product with pharmaceutical uses in various diseases. However, additional research related to the assessment of efficient extraction methods and characterization, particularly the evaluation of the mechanisms of action in new in vivo models, is necessary to confirm these findings and development of new drugs with therapeutic use.

BACKGROUND: Allium sativum L., or garlic, is one of the most studied plants worldwide within the field of traditional medicine. Current interests lie in the potential use of garlic as a preventive measure and adjuvant treatment for viral infections, e.g., SARS-CoV-2. Even though it cannot be presented as a single treatment, its beneficial effects are beyond doubt. The World Health Organization has deemed it an essential part of any balanced diet with immunomodulatory properties. OBJECTIVE: The aim of the study was to review the literature on the effects of garlic compounds and preparations on immunomodulation and viral infection management, with emphasis on SARS-CoV- -2. METHODS: Exhaustive literature search has been carried out on electronic databases. CONCLUSION: Garlic is a fundamental part of a well-balanced diet which helps maintain general good health. The reported information regarding garlic's ability to beneficially modulate inflammation and the immune system is encouraging. Nonetheless, more efforts must be made to understand the actual medicinal properties and mechanisms of action of the compounds found in this plant to inhibit or diminish viral infections, particularly SARS-CoV-2. Based on our findings, we propose a series of innovative strategies to achieve such a challenge in the near future.
