Rehmannia root is often used in conditions like fever, fluid exhaustion, consumptive diseases, bleedings, anemia, dizziness, palpitations, and menstrual disorders.
Rehmannia root is an important ingredient for clearing heat, cooling blood and stop bleeding.
According to TCM theory, infectious diseases are associated with external pathogens attacking the inner body (entering the nutrient and blood stages), individuals may have high fever, a red tongue, bleeding under the skin, or vomiting blood or nose bleeding. Rehmannia root can be used along with figwort root, peony root bark, red peony root and gardenia fruit in the remedies. An overheated digestive track may lead to pass bloody stool, which can be treated with rehmannia root along with golden thread rhizome, garden burnet root, and pagoda tree flower. Bloody urine may be due to damp-heat in the lower burner, which can be treated with rehmannia root combining with couch grass rhizome and field thistle herb. Uterine bleeding can also be a heat sign, in which rehmannia root can be used with baical skullcap root and cattail pollen. In addition, modern TCM often uses rehmannia root in the treatment of low blood platelet count.
Rehmannia root is an important ingredient for clearing heat, nourishing yin and promoting body fluid production.
After feverish conditions, some individuals may remain a persistent low fever that typically experienced in the evening, a disharmony named as yin deficiency in TCM. Physicians like to prescribe rehmannia root along with sweet wormwood herb, soft-shelled turtle carapace and anemarrhena rhizome for relief. When the individual has constipation or hard stools, then the herb can be used with dwarf lily-turf tuber and figwort root to smooth and lubricate the bowel movements; when there are poor appetite and mouth dryness, the herb can be used with coastal glehnia root, fragrant Solomonseal rhizome and germinated barley to promote the digestive secretions and functions.

Chinese yam is an ornamental vine that is native to Asia. It also grows in North America, but it isn't related to the sweet potatoes called yams that are popular there. Other names for Chinese yam are cinnamon vine, and shan yao.
Chinese yam is used in Chinese herbal medicine, traditionally to treat disorders related to the stomach, spleen, lungs, and kidneys.
The roots of Chinese yam contain diosgenin, which can be used to produce steroids such as estrogen and progesterone in a lab.
While the tuber and bulbs of Chinese yam are edible, generally only the tuber is consumed as food.
People with conditions related to the stomach, spleen, kidneys, lungs, or skin may benefit from Chinese yam. In addition to these uses, promoters of the herb claim it can be used as a remedy for many conditions, including:
1.hot flashes associated with menopause
