Aconite Carmichaeli is of the family Ranunculaceae and is indigenous to China where it has long history of usage. The source of it's first reference is thought to be the "Divine Husbandman's Classic of the Materia Medica" (Shen Nong Ben Cao Jing ) of the late Han period. It is often combined with other herbs in medicinal formulas. Some of these combinations are said to reduce the herbs overall toxicity. In Chinese medicine it is considered acrid, hot, and toxic.

It is usually harvested in the summer or winter. The toxicity of this herb varies greatly within different varieties. It also varies due to growing environment, the source of the herb, how and when it was harvested, preparation, and the length of time the herb was decocted.

Note: It is not recommended that you harvest or prepare Aconite Carmichaeli yourself, as even handling of the herb can have toxic effects.

What are the actions that have been associated with the herb?

Generally, aconite is thought to act as anodyne and diuretic. It may inhibit the growth of certain bacteria. It is thought to effect blood glucose levels and cardiac functions. Studies however, have shown conflicting results to date on it's effects in these areas.. It has sedative and narcotic actions and is highly toxic if handled incorrectly. There have been reports that the estimated adult fatal dosage may be as low as 1 grm. Other sources estimate a fatal dosage to be 10-60grms. Differences in estimates may be due to the different varieties of aconite, harvesting, preparation, treatment of the herb, and the "model" used to make the estimate.
