"Saengjihwang", one of the three great medicines of the emperor

The medicinal crop Rehmannia is said to be good for the body, so it is called as a pronoun of herbal medicine.

The Rural Development Administration (Chairman Heo Tae-woong, hereafter referred to as the Rural Development Administration) recommended that people know and use the efficacy and use of the medicinal plant 'Rehmannia' for the health of modern people who are exhausted from stress.

In oriental medicine, a drug that boosts the weakness of the body resulting from the imbalance of physiological functions is called a suppository. Rehmannia is a crop essential to the prescription of various herbal remedies, including Kyung-ok-ko, which is a medicine for the royal family of the Joseon Dynasty.

In ‘Shinnong Bonchogyeong’, Jihwang is described as ‘jisu (地髓)’ and ‘the essence of the earth’, which means that it contains the energy of the earth.

Rehmannia has different names and effects depending on the processing method. Raw saengjihwang (生地黃), raw dried geonjihwang (乾地黃), and steamed and dried with alcohol is called Sukjihwang (熟地黃).

Saengjihwang and Geonjihwang are both cold in nature and sweet in taste, but Saengjihwang is slightly bitter than Geonjihwang. It treats symptoms caused by heart, liver, and kidney dysfunction, and plays a role in replenishing body fluids while lowering body heat.

Rehmannia includes ingredients such as catalpol and stachyose, and catalpol is known to have diuretic and blood sugar lowering (lowering) effects.

Saengjihwang helps the eye health of modern people who watch a lot of print and video. In Donguibogam, an oriental medicine book, jihwangjuk is introduced as a dietary therapy to lower fever to treat 'symptoms such as blood and swelling in the eyes when waking up.' Rehmannia porridge is a thin porridge made from non-glutinous rice marinated in raw jihwang juice.




Sulfuric acid is slightly warm in nature and has a sweet taste. It treats symptoms caused by impaired liver and kidney function, and is often used as a restorative because it supplements body fluids including blood.

The ingredients of Sukjihwang are similar to those of raw jihwang and dried turmeric, 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 saengjihwang and geonjihwang in improving peripheral circulation disorders and promoting bone formation.

Sukjihwang is helpful in alleviating chest palpitations and anxiety symptoms. Put it in water, brew it thinly, and drink it as a tea.


Kim Dong-hwi, head of the ginseng special use team at the National Institute of Horticultural and Herbal Science, Rural Development Administration, said, “I recommend turmeric as an adjunct therapy to strengthen the stamina of modern people suffering from chronic stress.
