Astragalus Root

Astragalus membranaceus, one of the most emblematic plants of the Chinese pharmacopoeia.

Harvested in autumn from 4- to 5-year-old specimens in northern China and in Mongolia, its long, golden-yellow taproot is sliced across.

The “large slices” (Da) format corresponds to the traditional cut into thick sections that keeps the radial structure visible: quality is judged by the bright yellow colour, the thickness of the bark and the fibrous but supple texture.

Its mild scent recalls the legume, its savour is sweet.

A first-rank material of the Qi supplementing register, set apart from Ren Shen by its action at the surface: Huang Qi is attached above all to the Wei Qi, the defensive Qi of the surface.

Traditionally used for constitutions of deficient Qi, when the surface no longer holds the Liquids (Jin Ye) and the Wei Qi struggles to guard it.

It also raises the clear Yang (the material the tradition sets against a collapse of the Qi).

• Long decoction: 9 to 30 g (up to 60 g in intensive use), simmer for 40 to 60 minutes
• Yu Ping Feng San: a classic blend with Bai Zhu and Fang Feng, attached to the Wei Qi of sensitive constitutions
• Bu Zhong Yi Qi Tang: raising the clear Yang in constitutions of deficient Qi with a collapse of the energy
• Simmered broths: slices simmered in soups for 2 hours, a family tradition of northern China

To be avoided in cases of marked fullness (excess Yang rising, agitation, active accumulations) or at the acute stage of an attack on the surface.

Ask a practitioner for advice where there is stagnation: Huang Qi can supplement the Qi without freeing the blockages.
