What are the effects and functions of Chinese yam?

There are many functions and effects of Chinese yam, especially for female friends, it can effectively help them treat and solve some gynecological diseases, and is used for common vaginal itching, or liver and kidney yin deficiency, mental loss and other symptoms.

1. Wild Smilax glabra is good at treating sores caused by damp heat. Vulvar pruritus is a common disease among women. Symptoms include itching of the vulva and vagina, which may be unbearable and painful, causing restlessness or increased vaginal discharge. It is also called "vulvar pruritus". Vaginal itching is caused by liver-kidney yin deficiency, loss of essence and blood, and malnutrition of the vulva, which is a deficiency syndrome. Vaginal itching is caused by dampness and heat in the liver meridians, which causes leucorrhea to soak the vulva, or dampness and heat give rise to worms, which eat into the vulva and cause vulva itching, which is an excess syndrome. The latter is more common in clinical practice. I often use Zaoshi Zhiyang Decoction to treat it, and it usually works immediately.

2. Recipe: 30 grams of wild yam, 10 grams of betel nut, 15 grams each of sophora flavescens, honeysuckle vine, plantain, Kochia scoparia, angelica, white peony root, phellodendron, atractylodes, Dictamni bark, turmeric bark, Sichuan pepper, and Stemona bulb, and 10 grams of licorice. Take 1 dose daily, for external washing of the vulva, or sitz bath, once in the morning and once in the evening, each time for 15 to 30 minutes. The longer the time, the better the effect. Generally, vaginal itching can be eliminated after 5 consecutive doses.

3. The prescription makes heavy use of wild yam because it can detoxify and eliminate dampness, and is good at treating sores; honeysuckle vine, plantain, Kochia scoparia, white peony root are used to clear away heat and eliminate dampness; angelica, sophora flavescens, phellodendron, and atractylodes are used to clear away heat and dampness; areca nut, Dictamni bark, Hibiscus sabdariffa, Sichuan pepper, and Stemona japonica are used to kill insects and relieve itching, so the effect is quite quick.

4. Wild yam has the effect of clearing away heat and stopping leukorrhea. To treat damp-heat in the lower abdomen of women, with tofu-dregs-like vaginal discharge and yellow discharge with a fishy odor, I devised a prescription called Tufuling Yihuang Decoction. The prescription uses: 30 grams each of Tufuling and Astragalus, 15 grams each of honeysuckle, forsythia, angelica, Patrinia, wax gourd peel, coix seed, phellodendron, red vine, atractylodes, toon root bark, and atractylodes, and 5 grams of licorice. Take 1 dose daily, decocted in water, once in the morning and once in the evening. After years of clinical verification, it has proven to have reliable therapeutic effects.
