Dietary taboos of Rehmannia glutinosa

The medicinal material Rehmannia root is quite common in our lives. It is generally used to treat diseases such as kidney deficiency or imbalance of yin and yang. Although Rehmannia root has many functions, it can easily cause side effects. In particular, Rehmannia root should not be eaten with radish, three white ingredients, etc. It is also not allowed to be eaten by patients with typhoid fever. Therefore, I hope everyone can have a certain understanding of the dietary taboos of Rehmannia root.

No copper or iron utensils are allowed during processing and cooking.

"Leigong's Explanation of the Properties of Medicinal Materials" says: "Pick raw Rehmannia root, remove the white skin, steam it in a willow wood steamer on a ceramic pot, let the steam die, mix with wine, steam it again, and let it dry. Do not expose it to copper or iron, as it will cause kidney failure and gray hair, damage the blood circulation in men and the defense system in women." Do not allow copper or iron to be seen during the processing of cooked Rehmannia root. Do not use iron pots or kettles for decoction. "Yaojian" states: "If it comes into contact with iron containers, it will cause kidney failure." The storage should be as stated in "Bencao Congxin": "It tastes sweet like honey and must be stored in porcelain containers because it is fat, soft and moist."

Avoid radish, three whites, and blood when taking it.

"Essentials of Compendium of Materia Medica" records: Avoid eating radish, green onion, leek and scallion. "Essential Medicinal Materials and Their Dosages" says "Avoid radish, onion, garlic, and all kinds of blood." Radish seeds can reduce Qi, while Panax notoginseng can disperse Qi, which affects the nourishing effect of Rehmannia root. All blood is a product of flesh and blood, and it is advisable to avoid consuming it for fear that it may be too greasy.

It is not suitable for patients with typhoid fever.

In the case of typhoid fever, the pathogenic factors enter from outside, so it is better to disperse them rather than tonic them. As stated in the "Shen Nong's Herbal Classics: Records of 100 Kinds of Medicine", "Among the 113 prescriptions in Zhang Zhongjing's "Treatise on Febrile Diseases", only Rehmannia root is used to treat typhoid fever. In cases of febrile disease, the pathogen enters from the outside, and the most taboo is nourishment and stagnation. Even if tonic is used, it must have the property of dispersing and expanding. Otherwise, the pathogen will move inward, and there will be harm. Nowadays, when people see the symptoms that are slightly related to the virtual signs, they often use Liuwei Decoction, which kills people like hemp, which is really a sigh."

People with spleen deficiency, excessive phlegm and qi stagnation should take it with caution.

Rehmannia root is sweet in taste and especially nourishing in nature. It should be used with caution by those with spleen deficiency, excessive phlegm and qi stagnation. "Bencao Congxin" says: "Rehmannia root is stagnant in nature. It can block the chest and diaphragm for people with excessive phlegm and qi stagnation, so its use should be cautious." "Bencao Zhengyao" says: "Rehmannia root is stagnant in nature. It can block the chest and diaphragm for people with excessive phlegm and qi stagnation, so its use should be cautious." "Bencao Tongxuan" says: "Rehmannia root is stagnant in nature. It may block the chest and diaphragm for people with excessive phlegm, so it should be stir-fried with ginger juice to control the stagnation. It should also be supplemented with Amomum villosum and Agarwood, both of which can absorb qi and return to the kidney, and can also relieve the stagnation of Rehmannia root. This is the balance of using medicines."

This article tells us in detail the dietary taboos of Rehmannia glutinosa. I hope that after reading it, everyone can remember the precautions of Rehmannia glutinosa to avoid affecting the treatment of the body. If we have symptoms of spleen deficiency, excessive phlegm, or typhoid fever, we should not take Rehmannia root. We should also pay attention that Rehmannia root should not be eaten together with leeks, onions, and other foods.
