Plants of genus Stemona (Stemonaceae) have been long used locally and traditionally in many South and East Asian counties to relieve cough, dispel phlegm, prevent asthma, control pests, diminish inflammation, decrease pain, and treat some cutaneous diseases. ⋯ Though plants of genus Stemona have been put to enormous traditional uses, the pharmacological studies conducted were insufficient. Therefore, more secondary metabolites need to be studied for more detailed pharmacological studies. Further studies are also required to establish the mechanisms which mediate the plants' bioactivities in relation to the medicinal uses as well as investigate any potential toxicity for future clinical studies.

Scutellaria (Lamiaceae), which includes approximately 360-469 accepted species, is widespread in Europe, North America, East Asia, and South America. Several species have a long history being used as traditional medicines to treat respiratory, peptic, neurological, and hepatic and gall diseases. The phytochemistry and pharmacology of the genus Scutellaria have been developed dramatically in the past ten years, and the traditional uses and clinical studies of the genus have not been systematically summarized. Therefore, it is especially valuable to review the current state of knowledge to provide a basis for further exploration of its medicinal potential. ⋯ The species included in the genus Scutellaria can be used to treat cancer, infection, hepatic disorders, cardiovascular and cerebrovascular diseases, neurodegenerative diseases, and other diseases. Some indications in traditional medicines have been confirmed by modern pharmacological studies, such as anticancer, anti-inflammatory, anti-infective activity, and hepatoprotective and neuroprotective effects. The available literature indicated that most of the bioactivities could be attributed to flavonoids and neo-clerodane diterpenoids. Although there are some uses of Scutellaria in clinical practice, the existing research on this genus is still limited. In order to expand the development of medicinal resources of Scutellaria, the already studied species in this genus are recommended for more comprehensive investigation on their active substances, pharmacological mechanisms, quality control, clinical use and new drug research. Additionally, it is necessary to study species that their chemical composition or pharmacological activity have not yet been investigated, especially those used in folk medicine.

The genus Stellera Linn. consists of species of perennial herbs and shrubs, and is mainly distributed in the temperate regions of east Asia to west Asia. There are 10∼12 species in the world, two species in China: Stellera chamaejasme Linn. and Stellera formosana Hayata ex Li. As recorded, the roots of Stellera species are used to dissipate phlegm and relieve pain. The roots and the barks can be used for papermaking. ⋯ This paper reviewed the ethnopharmacological uses, chemical constituents, pharmacology, clinical applications and toxicology of the genus Stellera. The genus Stellera has broad application prospects. However, further in-depth studies are needed to determine the medical uses of the genus and its chemical constituents, pharmacological activities, clinical applications and toxicology.

Kanglaite (KLT) is an active extract of the Coix lacryma-jobi seed, which can benefit Qi and nourish Yin, and disperse the accumulation of evils. It is used as a biphasic broad-spectrum anti-cancer drug, and shows synergistic effects with radiotherapy and chemotherapy. However, the mechanism of KLT combined with cisplatin (CDDP) against hepatocellular carcinoma (HCC) has not been elucidated. ⋯ KLT pretreatment may increase the effects of CDDP on HepG2 cells, by exhibiting cooperative effects on suppression of HepG2 cells. The mechanisms may partly by inhibiting CKLF1 mediated NF-κB pathway, which may contribute to inflammation of tumor microenvironment and chemoresistance of CDDP. Inhibition of transporter-mediated drug efflux is also involved in KLT mediated sensitization effects of CDDP.

Cereus hildmannianus (K.) Schum. (syn. C. peruvianus) is a native medicinal plant in the Neotropical region. C. hildmannianus cladodes extracts are used in folk medicine for weight loss, reducing cholesterol, low-density lipoprotein (LDL) levels, as diuretic and cardiotonic, and to treat various diseases, including pulmonary disorders, rheumatism, and in topical treatment for wounds and lithiasis. Fruits and flowers of C. hildmmanianus have high nutritional value. ⋯ In traditional medicine, C.hildmannianus is used to treat various diseases, including pulmonary disorders, rheumatism, and in topical treatment for wounds and lithiasis. The extracts from the cladodes of C. hildmannianus exhibited numerous in vitro and in vivo pharmacological activities such as gastroprotective, antioxidant, antifungal, ovicidal, hemagglutinating and slimming, and anticancer activity. These extracts' substances belong to different classes of chemical compounds such as fatty acids, polysaccharides, terpenes, alkaloids, phenolic acids, and flavonoids CONCLUSIONS: Ethnomedicinal surveys have indicated the use of C. hildmannianus, an important medicinal plant in South America, for the treatment of various diseases. The ethnobotanical, phytochemical, pharmacological, and ethnomedicinal properties from various morphological parts of the plant of C. hildmannianus were highlighted in this review, which provides information for future studies, commercial exploration and reveals that this plant has a huge potential for pharmaceutical and nutraceutical applications.
