Can Rehmannia be steeped in water for consumption?

Generally speaking, Rehmannia can be consumed as a tea infusion, but whether it is suitable depends on individual body constitution and specific circumstances.

Rehmannia is divided into two types: raw Rehmannia and prepared Rehmannia. These two forms differ in nature and function. Raw Rehmannia is cold in nature and functions to clear heat, cool the blood, nourish yin, and promote body fluid production. It is suitable for symptoms such as dry mouth and throat or sore throat caused by heat-related illnesses. Prepared Rehmannia, on the other hand, has undergone processing and is warm in nature. Its main functions are nourishing yin, enriching blood, and replenishing essence and marrow. It is suitable for individuals with blood deficiency or kidney yin deficiency. Drinking Rehmannia as a tea infusion can extract its active components and help regulate body functions.

If an individual has a cold body constitution or weak spleen and stomach, the cold nature of raw Rehmannia may cause diarrhea or indigestion. Prepared Rehmannia is relatively rich and greasy in nature, and long-term or excessive consumption may affect spleen and stomach function. Individuals with excessive dampness in the body should be especially cautious.

Although Rehmannia is a commonly used traditional Chinese herb, it should be consumed in moderation as a tea infusion, with dosage adjusted according to individual constitution. When necessary, consult a professional physician to ensure safety.
