② Treatment of lumbar and joint pain: Chinese wolfberry leaf, wine drink. (Hunan medical records)

[discussion by famous experts] 1. In the book of Materia Medica, it is said that "the Chinese wolfberry is not dominated by the smell. However, according to Chen's collection, it should be bitter, cold and nontoxic. The smell is all Yin. It's also a medicine that enters the liver and kidney. Only when it enters the liver, it is the main cause of vitiligo. Covering the liver is the place of wind and wood. It is the viscera of storing blood. If the blood is deficient, it will produce fever. If the heat is very hot, it will produce wind. Bitter cold can cool the blood and clear the heat, so it is the main cause of vitiligo. If the kidney is weak, it will multiply the dampness and heat, and the waist and knee will be disadvantageous. If the kidney is strong, it will be hot and soft. Therefore, it has strong sexual desire, and it is hard to eat bitter. The bitter taste of this medicine enters into the kidney, which is why it wants to strengthen the nature of the ear. "The secret recipe is very effective in treating phlegm fire. The fire of covering phlegm is not caused by the fire of yin deficiency, burning the lung and boiling the dross. This medicine goes straight into the foot Shaoyin meridian to nourish Yin Qi, then the phlegm and fire will disappear, which is the meaning of drawing money from the bottom of the pot. It can also disperse wind, poison and sores. In the past, I had been suffering from Myrica rubra poisoning for 30 years. After taking this medicine, the sores healed and the color became less. All of them used its function of clearing away heat and cooling blood. "

② "Ben Jing Feng Yuan": "Gougu", "Ben Jing" and "Ben Cao" are all mistakenly listed as "Ligustrum lucidum". It tastes bitter and sweet. It has the functions of tonifying Zhong'an and five Zang, nourishing spirit, and eliminating all kinds of diseases. Is it as good as above to treat the essence of Ligustrum lucidum? Today, when you use a few Jin of Ligustrum lucidum, you can prick it and put two or three jin of jujube into it. You can boil the ointment and collect the honey. It is often effective in treating fatigue, blood loss and flaccidity. It can nourish the blood gas without suffering from injury. "
