“Saeng Rehmannia glutinosa”, one of the emperor’s three major health remedies

The medicinal crop Rehmannia glutinosa is said to be good for the body, so it is called a synonym for restorative medicine. It is known as a crop that does not suffer from various tonic prescriptions, and it would be good to use it after knowing where it is good for our body.

The Rural Development Administration (Director Heo Tae-woong, hereinafter referred to as Rural Development Administration) recommended that modern people who are tired from stress learn about the efficacy and use of the medicinal crop ‘Rehmannia glutinosa’ and use it to improve their health.

In Oriental medicine, drugs that strengthen the body's weak state caused by imbalance in physiological functions are called tonics. Rehmannia glutinosa is a crop that is indispensable in various tonic prescriptions, including Kyung-ok-ko, a tonic for the Joseon royal family.

In the ‘Shennong Bencao Classic’, Rehmannia glutinosa is described as ‘the body of the earth’ and ‘the essence of the earth,’ which means that Rehmannia glutinosa contains the energy of the earth.

Rehmannia glutinosa's name and efficacy vary depending on the processing method. The raw rehmannia glutinosa is called raw rehmannia glutinosa, the raw dried rehmannia glutinosa is dried rehmannia glutinosa, and the dried rehmannia glutinosa is steamed and dried with alcohol.

Both fresh and dried Rehmannia glutinosa are cold in nature and sweet in taste, but fresh Rehmannia glutinosa is slightly more bitter than dried Rehmannia glutinosa. It treats symptoms caused by poor heart, liver, and kidney function, reduces body heat, and replenishes body fluids.

Rehmannia glutinosa contains ingredients such as catalpol and stachyose, and catalpol in particular is known to have diuretic and blood sugar lowering effects.

Rehmannia glutinosa helps with the eye health of modern people who read a lot of print and video. Donguibogam, a book on oriental medicine, introduces Rehmannia glutinosa as a dietary treatment to reduce fever to treat ‘symptoms such as bloodshot and swollen eyes when waking up from sleep.’ Rehmannia glutinosa is a thin porridge made from non-glutinous rice marinated in raw rehmannia juice.

Rehmannia glutinosa is slightly warm in nature and sweet in taste. It treats symptoms caused by decreased liver and kidney function and is often used as a tonic because it supplements body fluids, including blood.

The ingredients of ripe Rehmannia glutinosa are similar to fresh and dried Rehmannia glutinosa, but as the steaming and drying process is repeated, the content of stachyose and catalpol decreases and monosaccharides (5-HMF) are produced. It is known to be superior to fresh and dried Rehmannia glutinosa in improving peripheral circulation disorders and promoting bone formation.

Rehmannia glutinosa helps improve heart palpitations and anxiety symptoms. Add it to water, steep it thinly, and drink it as tea.


Kim Dong-hwi, head of the ginseng special use team at the National Institute of Horticultural and Herbal Science under the Rural Development Administration, said, “I recommend Rehmannia glutinosa as an auxiliary treatment to strengthen the physical strength of modern people suffering from chronic stress.
