Li Shizhen said in Compendium of Materia Medica that "(fat) hemp is rich in oil and black is used as medicine, hence the name" black (fat) hemp ". Later generations may gradually spread to black sesame for convenience of writing or other reasons.
Chinese medicine believes that black sesame is sweet and flat, and it passes through the liver and kidney as medicine. If eaten regularly, it can play a certain role in "tonifying liver and kidney".
Therefore, if you eat black sesame seeds often, it still has a certain kidney-tonifying effect.
As for the efficacy record and application of black sesame, in fact, black sesame has a long history of being used as medicine. As early as in Shennong Materia Medica, it was recorded that black sesame can "replenish the five internal organs, invigorate qi, promote granulation and nourish the brain", and long-term consumption can help people keep fit and stay young.
The Classic of Materia Medica says that black sesame is "a good valley for nourishing the spleen and stomach and tonifying the liver and kidney". If eaten regularly in daily life, it is good for the spleen and stomach, liver and kidney and other organs of the human body.
For example, people with insufficient liver and kidney and insufficient essence and blood are very prone to premature whitening and premature hair loss. Many places will use black sesame seeds to alleviate it.
In Qian Jin Fang, there is a health care prescription called Wuma Pill, which is made by steaming black sesame seeds, drying them in the sun and grinding them into powder, and then making them into pills with jujube meat. It is beneficial to liver and kidney and has the effect of blackening hair.
For poor eyesight, blurred vision and dry skin caused by liver and kidney deficiency, Chinese medicine makes black sesame seeds and frosted mulberry leaves into pills, which can tonify liver and kidney, improve eyesight and moisturize skin.
In addition, the ancients also regarded black sesame as a nourishing product, which can alleviate skin edema and insufficient blood and essence caused by malnutrition.
In order to alleviate this situation, the ancients often cooked porridge with black sesame seeds, or made nutritious cakes with jujube and flour, which improved the deficiency caused by insufficient nutrition to some extent.
