In recent years, research has found that the root of Zhea fungus contains flavonoids, polysaccharides and other ingredients, which have antioxidant and immunomodulatory effects. Animal experiments show that its extract can lower blood sugar (see table below), but human clinical data are limited. In addition, its diuretic effect is related to its high potassium content, so it is suitable for people with edema to consume in moderation. It should be emphasized that these effects are mostly auxiliary and cannot replace drug treatment.

Consumption suggestions: balance of deliciousness and efficacy

Zheergen can be eaten cold, cooked in soup or stir-fried. In Yunnan and Guizhou regions, it is often mixed with chili and soy sauce to neutralize the coldness. It is recommended that the daily intake of fresh food should not exceed 100 grams and avoid eating on an empty stomach. Pregnant women and those with allergies should consult a physician first.

Traditional experience and modern research have jointly confirmed its antibacterial and anti-inflammatory properties, while the therapeutic effect requires long-term appropriate dosage to be realized. When using it, you need to consider your physical condition and follow medical advice when necessary, so that the true value of this natural resource can be unleashed.
