Yerba mansa or lizard tail (Anemopsis californica) is a perennial flowering plant within the family Saururaceae. It is the only species in the monotypic genus Anemopsis. It is native to southwestern North America. The conic white 'flowers' (actually reduced inflorescences, or pseudanthia) are borne in early spring, and are surrounded by 4-9 large white bracts.[1] As it matures, the visible part of the plant develops red stains, eventually turning bright red in the fall.

In her book on herbs of the southwestern USA, Dr. Soule discusses the common name. ". . . Yerba mansa is one of those names which confounds linguists. Yerba is Spanish for herb, and thus one would think that mansa is also from Spanish as well, but all indications point to the fact that it is not. Mansa means calm or tranquil in Spanish, and the plant has no sedative effect, nor did local people ever use it as a calming agent. Its primary use is as an antimicrobial, antibacterial, and antifungal. The most likely explanation is that mansa is a Spanish alteration of the original native word for the plant, now lost in the depths of time. . ." Quoted here by permission of the author.[3]
Perhaps there is some connection to the Manso Indians
Yerba mansa is showy in spring when in bloom. Similar to the sunflower family, what appears to be a single bloom is in reality a dense cluster of individually small flowers borne in an inflorescence. In this species the inflorescence is conical and has five to ten large white bracts beneath it, so that along with the tiny white florets, the whole structure is quite striking when it blooms in spring. The conical structure develops into a tough capsule that can be carried downstream to spread the tiny, pepper-like seeds.[4]
Yerba mansa is used as an antimicrobial, an antibacterial, and to treat vaginal candidiasis.[2][5]
Yerba mansa is used to treat inflammation of the mucous membranes, swollen gums and sore throat. An infusion of roots can be taken as a diuretic to treat rheumatic diseases like gout by ridding the body of excess uric acid, which causes painful inflammation of the joints. Yerba mansa prevents the buildup of uric acid crystals in the kidneys which could causes kidney stones if left untreated. A powder of dried root can be sprinkled on infected areas to alleviate athlete's foot or diaper rash.[6][7]
Yerba mansa is versatile, it can be taken orally as a tea, tincture, infusion or dried in capsule form. It can be used externally for soaking inflamed or infected areas. It can be ground and used as a dusting powder. Some people in Las Cruces, NM use the leaves to make a poultice to relieve muscle swelling and inflammation.[8]
