The main group of the Yakushi Clan, the Medicine Men Sect, is composed of bird yōkai whose leader is considered to be the commander of medicines and poisons. By dipping their feathers in alcohol, one can create a potent poison, and the Medicine Men Sect is able to turn any medicine poisonous. At birth, these yōkai are beautiful birds, and their wings only become poisonous when they come of age. As a result, they have weak bodies and short lifespans.
The main building of their headquarters was burned down in 2009 by Hebidayu and his supporters, but has since been rebuilt with the help of the Nura main house.
