Self-Nanoemulsifying Drug Delivery System (SNEDDS) Using Lipophilic Extract of Viscum album subsp. austriacum (Wiesb.) Vollm.

Background and Purpose: Natural products are potential sources of anticancer components. Among various species, the lipophilic extract of the Viscum album subsp. austriacum (Wiesb.) Vollm. (VALE) has shown promising therapeutic potential. The present work aimed to qualify the plant source and characterize the extract's chemical profile. In addition, a self-nanoemulsifying drug delivery system (SNEDDS) containing VALE (SNEDDS-VALE) was developed. Methods: V. album subsp. austriacum histochemistry was performed, and the chemical profile of VALE was analyzed by GC-MS. After the SNEEDS-VALE development, its morphology was visualized by transmission electron microscopy (TEM), while its stability was evaluated by the average droplet size, polydispersity index (PdI) and pH. Lastly, SNEDDS-VALE chemical stability was evaluated by LC-DAD-MS. Results: The histochemical analysis showed the presence of lipophilic compounds in the leaves and stems. The major compound in the VALE was oleanolic acid, followed by lupeol acetate and ursolic acid. SNEDDS was composed of medium chain triglyceride and Kolliphor® RH 40 (PEG-40 hydrogenated castor oil). A homogeneous, isotropic and stable nanoemulsion was obtained, with an average size of 36.87 ± 1.04 nm and PdI of 0.14 ± 0.02, for 14 weeks. Conclusion: This is the first histochemistry analysis of V. album subsp. austriacum growing on Pinus sylvestris L. which provided detailed information regarding its lipophilic compounds. A homogeneous, isotropic and stable SNEDDS-VALE was obtained to improve the low water solubility of VALE. Further, in vitro and in vivo experiments should be performed, in order to evaluate the antitumoral potential of SNEDDS-VALE.

The use of homeopathy and flower therapy as an aid in the treatment of climacteric symptoms: an integrative review

Climacteric is characterized as the set of symptoms that usually start in the period of transition from the reproductive phase to female senility, and directly impacts woman's quality of life. Currently, the treatments approved by the FDA for this pathology mainly involve the use of antidepressants and hormone replacement, both having side effects. Clinical studies carried out in 2002, showed an increased risk of breast cancer, and other pathologies related to the prolonged use of these drugs. The impact ofthe studies resulted in a greater interest in complementary and alternative medicines (CAMs), such as the use of homeopathy and flower remedies for the treatment of climacteric symptoms. This abstract aims to present an integrative review on the use of homeopathy and flower remedies in the treatment of climacteric symptoms, in order to identify it main scientific evidence. For this, metodology consisted of research in the databases Web of Science, Google Scholar, HomeoIndex, LILACS and SciELO. The inclusion criteria were original human studies, totally available, and published in the last 10 years in Portuguese, English and Spanish, presenting the use of floral remedies or homeopathic treatment. The main homeopathic medicines used were Lachesis mutus, Belladona, Sepia officinalis, Sanguinaria canadensis and Sulfur. The main flower remedies were Cherry plum, Agrimony, Gentian, Walnut, Olive and Larch. The findings in this review demonstrate a positive outcome trend in favor of the effectiveness of these practices through the studies evaluated, encouraging the expansion of new designs and research that fully contemplate the principles of these practices. Thus, this work contributes to the advancement in the understanding of each one of these rationalities, making this work a source of consultation for health professionals and for future research, resulting in a strengthening of CAMs in the field of health.
