Dong Quai: Benefits, Dosage & What the Science Says

Dong quai (Angelica sinensis) is one of the most important herbs in TCM's pharmacopoeia, used for over 2,000 years as a blood-nourishing and circulation-supporting tonic. Modern research has identified phthalides and ferulic acid as key bioactives relevant to smooth muscle relaxation and antioxidant protection.
