Rehmannia, or Rehmannia glutinosa, is a popular herb in Chinese medicine. Also referred to as Chinese Foxglove, this plant has a history of over two thousand years of use, dating back to the Han Dynasty. Its leaves grow low to the ground, and it blooms with bell-shaped flowers ranging in colors from yellow to burgundy. According to Traditional Chinese Medicine, the key to good health is maintaining the balance between the two opposing forces in your body: yin and yang. This plant helps nourish the yin and is therefore a key component in many tonic formulas. And, in fact, the whole plant can be used medicinally. (1)

Here are, for example, 5 health uses of rehmannia:

1. Improves Kidney and Adrenal Function

Rehmannia (sometimes referred to as rehmannia root) has a strong association with adrenal and kidney health. In fact, it’s known as “the kidney’s own food.” According to Traditional Chinese Medicine, kidney imbalances can cause weakness in the legs, pain in the lower back, as well as loss of hearing. As this plant can restore adrenal function and purify the kidneys, it is considered to help these conditions. (2)

Furthermore, this plant can help improve urinary tract health, especially in men. It also combats autoimmune diseases such as fibromyalgia, rheumatoid arthritis, and multiple sclerosis. (3)

2. Helps Heal Broken Bones

3. Treats External and Internal Bleeding

Rehmannia has astringent properties which makes it useful for treating both external and internal bleeding. This covers such inflictions as ulcers, wounds, and nose bleeds, to name a few. The added bonus is that this plant will purify the blood and reduce the pressure in it. You can also use it to treat skin conditions like eczema and psoriasis. (5)
