Prepared Chuan Wu is also available.

This form of Aconite is the wild variety and is slightly more potent than Sichuan Aconite. Wild Aconite is acrid, bitter, and very hot. Non-prepared aconite is also very toxic and is only available in its processed form. It is also one of the most important herbs in the Materia Medica. While other herbs might have a hotter energy, Aconite defines the most yang herb of the Materia Medica.
