Overview
Cistanche is a parasitic plant that grows on the roots of desert shrubs (saxaul trees) in the arid deserts of northwest China. The thick, fleshy stems are dug in spring before they emerge from the ground. Known as "desert ginseng," it is a primary yang tonic in Chinese medicine, valued for its ability to tonify kidney yang without being too warming or drying.

Decoction: 6-15g daily (up to 30g for severe deficiency). Powder/Capsules: 2-6g daily. Wine: 30-50g steeped in rice wine, 15-30ml daily.
Quality & Storage
Harvest Season
Spring, before the stems emerge above ground (March-April). Dug by hand from the sand, cleaned, and dried in the sun or by low-temperature drying. Wild-harvested Cistanche is increasingly rare and protected.
Quality Indicators
Thick, fleshy stems that are brown/reddish-brown and have clear scales on the surface. The best quality ("Tian Cong Rong" from Hetian, Xinjiang) is thick, heavy, and soft. Sliced cistanche should show a dense, starchy cross-section. Avoid thin, woody stems.
