Chinese rhubarb

Rheum palmatum

Rheum palmatum is a perennial herb central to various traditional Asian medicinal practices. It is traditionally utilized as an aperient, astringent, and stomachic across several herbal traditions. Scientific evidence suggests that emodin may activate the CFTR chloride channel, which could provide a mechanism for its laxative effects. Some studies indicate that combining Chinese herbal medicine with Western medicine may improve clinical efficacy in certain respiratory conditions, though limitations exist in this data. Regarding safety, no major issues have been recorded, and there are currently no recorded drug interactions.
