Introduction to Plant Material
The raw material of this product is the dried root of the Apiaceae plant Glehnia littoralis F. Schmidt ex Miq. (Bei Sha Shen, coastal Glehnia root). It is mainly produced in coastal sandy areas of Shandong, Hebei, and Liaoning. The 2020 edition of the Chinese Pharmacopoeia (Part I) includes the standard for Bei Sha Shen. Bei Sha Shen is sweet and slightly bitter in taste and slightly cold in nature, traditionally used to nourish yin and clear the lungs, and to benefit the stomach and generate fluids.
Core Functions
The following functional summary is based on published scientific research and traditional applications. Specific functions should be evaluated in combination with the Glehnia Root Extract product form and dosage.
In traditional Chinese medicine, Bei Sha Shen is used to nourish yin and moisten the lungs, to benefit the stomach and generate fluids, suitable for daily adjustment of dry cough due to lung dryness and insufficient stomach yin.
Modern studies show that its polysaccharide components have certain immune-regulating effects, and its coumarin components exhibit antioxidant and anti-inflammatory activities. Relevant in vitro and animal experiments support its potential in immune support and oxidative stress management. Specific effects need to be comprehensively evaluated based on form, dosage, and population.
