Aconitum species are well-known for their medicinal value and high lethal toxicity in many Asian countries, notably China, India and Japan. The tubers are only used after processing in Traditional Chinese Medicine (TCM). They can be used safely and effectively with the methods of decoction, rational compatibility, and correct processing based on traditional experiences and new technologies. However, high toxicological risks still remain due to improper preparation and usage in China and other countries. Therefore, there is a need to clarify the methods of processing and compatibility to ensure their effectiveness and minimize the potential risks. ⋯ Using of the methods of rational preparation, reasonable compatibility, and proper processing based on traditional experiences and new technologies, can enable Aconitum to be used safely and effectively.

Plants of the genus Hymenaea (Fabaceae) are used in South American and Asian traditional medicines to treat a multitude of disorders, like cough, diarrhea, dysentery, intestinal colic, pulmonary weakness, asthma, anemia, sore throat, and for the treatment of kidney problems, viral related disorders, chronic cystitis, bronchitis, and bladder infections. Some Hymenaea species are also used as vermifuge, and for the treatment of arthritis, and inflammation conditions. This review deals with updated information on the traditional uses, phytochemistry and pharmacology of ethnomedicinally important Hymenaea species in order to provide an input for the future research prospects. ⋯ Plants of this genus have offered bioactive samples, both from crude extracts and pure compounds, thus substantiating their effectiveness in traditional medicine. However, intensive investigations of all the species of Hymenaea spp. relating to phytochemical and pharmacological properties, especially their mechanism of action, safety and efficacy could be the future introspection.

Clinacanthus nutans (Burm. f.) Lindau, a widely used medicinal plant, is extensively grown in tropical Asia and Southeast Asian countries. C. nutans, with its broad spectrum of pharmacological activities, has been traditionally used to treat cancer, inflammatory disorders, diabetes, insect bites, and skin problems, consumed as a vegetable, mixed with fresh juices, in concoctions, and as a whole plant. The present review analyzes the advances in the ethnopharmacology, phytochemistry, pharmacology, and toxicology of C. nutans. In addition, the needs and perspectives for future investigation of this plant are addressed. ⋯ The collected literatures demonstrated that, as an important traditional medicine, C. nutans is a promising ethnomedicinal plant with various extracts and bioactive compounds exhibiting multifarious bioactivities. However, it is important for future studies to conduct further in vitro and in vivo bioactivity evaluations systematically, following the standard pharmacology guidelines. It is crucial to elucidate in-depth molecular mechanisms, structure-activity relationships, and potential synergistic and antagonistic effects of multi-component extracts and bioactive constituents derived from C. nutans. Further studies should also focus on comprehensive toxicity that includes long-term effects and adverse effects on target organs of C. nutans and bioactive compounds in correlation with the specific pharmacological effects.

Atopic dermatitis (AD) is a chronic pruritic and inflammatory disease occurring in skin. Patrinia scabiosifolia Link (PS), a member of the Patrinia genus (Caprifoliaceae family), has traditionally been used in folk medicines to treat various inflammatory diseases such as acute appendicitis, ulcerative colitis, and pelvic inflammation in Korea and other parts of East Asia. ⋯ PS may attenuate the development of AD-like lesions by increasing filaggrin expression and lowering IgE and inflammatory cytokine levels. These results indicate the potential for development of a PS-based drug treatment for AD.

Salvia divinorum is a medicinal plant traditionally used in hallucinogenic ethnopharmacological practices and for its analgesic and antinflammatory properties. Its active compounds include diterpenes known as salvinorins which act as potent κ opioid receptor agonists. ⋯ The present investigation give evidence that SD is capable to reduce algesic response associated to neuropathic and inflammatory nociception. This study support therapeutic alternatives for a disabling health problem due to the long term pain with high impact on population and personal and social implications.
