Notopterygium incisum Ting ex H.T. Chang, known in Chinese as 'Qianghuo' is a traditional Chinese medicinal herb with the rhizome and roots associated with meridians of the kidney and urinary bladder. It is pungent, bitter and warm in nature. It has been used over the years to disperse cold, prevent painful obstructions from wind, damp and warm pain. It has also been used with other herbs to treat wind-cold exterior syndrome and wind-cold-damp bi-syndromes and has been known to grow well in regions of high altitude such as Gansu, Tibet etc. ⋯ In this paper, we have reviewed various researches conducted on N. incisum especially in areas of its ethnopharmacological use, phytochemicals, pharmacology and developed analytical methods. This herb has been used over the years in treating headache, rheumatoid arthritis, cold, diaphoretic etc, prompting many types of research into identifying which compounds are responsible for these activities and their mechanism of action. More research is needed in the area of pharmacokinetics and toxicology to give further information on the clinical use and control the quality of the herb.

Kidney deficiency is the main pathogenesis of osteoporosis based on the theory of "kidney governing bones" in traditional Chinese medicine (TCM). Combined Herba Epimedii and Fructus Ligustri Lucidi, based on traditional Chinese formula Er-Zhi pills, were frequently used in TCM formulas that were prescribed for kidney tonifying and bone strengthening. However, it is unclear whether the combination of the two herbs may have a protective influence on glucocorticoid-induced osteoporosis (GIOP). The objective of this study was to evaluate the therapeutic effects and the underlying molecular mechanism of the decoction and the active fractions of the combined herbs in GIOP rats. ⋯ Combination of Herba Epimedii and Fructus Ligustri Lucidi exhibited protective effects on promoting bone formation and precluding bone resorption. The underlying mechanism may be attributed to its regulations on TGF-β1/Smads pathway. The substance bases of the combined herbs on anti-osteoporosis were total flavonoids of Herba Epimedii, total iridoids and flavonoids of Fructus Ligustri Lucidi.
