Fu Zi (Zhi) (Aconitum carmichaelii praeparata), commonly known as Prepared Aconite Root, is a powerful warming herb in Traditional Chinese Medicine (TCM). For centuries, this classic Fu Zi herb has been valued for its traditional ability to restore devastated Yang, warm the fire, and dispel internal cold.

In classical Chinese medicine, only the properly processed form—Zhi Fu Zi—is used in herbal practice. Through traditional preparation methods, the raw root is transformed for use in formulas focused on deep cold patterns, Yang deficiency, and the restoration of warmth and movement.
Because of its intensely warming nature, Fu Zi in Chinese medicine is traditionally used when profound cold, weakness, or collapse of Yang is part of the underlying pattern.

Botanical Information
Botanical Name: Aconitum carmichaelii
Family: Ranunculaceae
Fu Zi is derived from the lateral root of a flowering perennial native to China. The raw root undergoes traditional processing methods such as boiling, steaming, or other preparation techniques to create the prepared medicinal form used in herbal practice.
The processed root is then dried and sliced for inclusion in formulas. Proper preparation has always been considered essential in traditional use.
Because this herb requires expert handling and preparation, it has historically been regarded as a specialized herb used by trained practitioners.
Historical Use of Fu Zi Herb

Historically, it has been valued in classical formulas intended for extreme cold patterns, collapse of Yang, cold limbs, and deeply weakened vitality. It appears prominently in major warming formulas from traditional materia medica and classical texts.
