Tou Gu Cao Tincture & Alcohol-Free Extract

Tou Gu Cao (Speranskia tuberculata) is a small perennial of the spurge family, Euphorbiaceae, native to northern China, where it grows on dry hillsides, sandy slopes and open scrub in Hebei, Shanxi and Shaanxi. It rises 15 to 50 cm from a woody rootstock with slender, hairy stems and alternate, oval to lanceolate, coarsely toothed leaves. Small green flowers are borne in terminal racemes, male above and female below, and the three-lobed capsules are covered in small warts, from which the species takes its name. The Chinese name means "bone-penetrating herb". We extract the dried herb.
