Abstract

Withania somnifera (L.) Dunal (Solanaceae), also known as ashwagandha, is an important medicinal plant that is widely used as a home remedy for several diseases in the Indian subcontinent and other parts of the world. W. somnifera is a dietary supplement composed of various nutrients, polyphenols and alkaloids that have free radical scavenging capacity, as well as other chemical constituents that possess anti-inflammatory, antitumor, anti-stress, antioxidant, immunomodulatory, and rejuvenating properties. The mechanism of action for these properties are not fully understood. W. somnifera also appears to influence the endocrine, cardiopulmonary and central nervous systems. Toxicity studies reveal that W. somnifera can be used without side effects. The findings presented in this review are very encouraging and indicate that this herb should be studied more extensively to confirm these results and to reveal other potential therapeutic effects.

Predictions of the Biological Effects of Several Acyclic Monoterpenes as Chemical Constituents of Essential Oils Extracted from Plants

Daniela Dascalu, Adriana Isvoran, Nicoleta Ianovici

Summary: This study uses a computational approach to predict the biological and toxicological effects of nine acyclic monoterpenes. The results indicate that these compounds are generally safe for humans, except for their potential inhibitory effect on CYP2B6. However, they may cause skin and eye irritation, toxicity through respiration, and skin sensitization. Therefore, further in vivo studies are needed to better understand the pharmacokinetics and toxicological properties of acyclic monoterpenes and their clinical relevance.
