- Polysaccharides (mucilage & inulin) are soothing to the digestive tract and an immunostimulant.
- Sesquiterpene lactone arctiopicrin is a bitter glycoside and antibacterial.
- Lignans (arctigenin) exhibits anti-inflammatory activities by inhibiting inducible nitric oxide synthase (iNOS) via modulation of several cytokines, and is gastroprotective. Lappaol F exhibits anti-tumor activity in vitro and in vivo and is considered to have strong potential to be developed as an anticancer therapeutic.
- Decoction: 1 tsp root/cup, simmer 20 minutes, 1 cup TID for several weeks.
- Tincture: (1:2, 40%), 2-4 ml QD, 25 ml weekly max.
