Comment:
1. TCM uses the root of a Gromwell species, L. erythrorhizon Zi Cao (which is regarded by some as a subspecies of L. officinale). It cools the Blood, clears Heat and Toxin and is primarily used to promote the expression of rashes such as Measles and Chicken Pox. It is also used for urinary dysfunction and Damp-Heat Leukorrhea. The Western and Eastern species are closely related and similar in appearance. The Western species is primarily used for Urinary disorders and the Chinese species for Skin rashes, but they are probably fairly synonymous.
2. Arnebia species are used as Zi Cao in some parts of China. They are also used in Tibetan Medicine (A. euchroma is called ‘Bri mog འབྲི་མོག་, A. guttata is called ‘Bri rdzud འབྲི་རྫུད་) where they are mainly used for bleeding from the Lungs and increase of ‘unhealthy Blood’.
Substitute:
Arnebia euchroma and A. guttata are used for Zi Cao in some parts of China.
