Ligusticum

Ligusticum (lovage,:824 licorice root) is a genus of about 60 species of flowering plants in the family Apiaceae, native to cool temperate regions of the Northern Hemisphere. Its name is believed to derive from the Italian region of Liguria. The roots of several species are used as medicinal herbs. L. wallichii is one of the 50 fundamental herbs used in Chinese herbology, where it is called chuānxiōng (川芎); in English, Szechwan lovage. L. porteri (osha) is used in Western herbal medicine. Chinese Ligusticum root contains alkaloids that have been shown in studies to inhibit TNF-alpha production and TNF-alpha-mediated NF-kappaB activation. One study conducted in Japan showed the active compounds found in Ligusticum sinense have both anti-inflammatory and pain-reducing effects, exerting its anti-inflammatory benefits in the early and the late stages of processes in the inflammatory pathology. Both Ligusticum sinense and L. jeholens essential oils contain natural antimicrobial and antioxidant agents.
