Chinese medicine believes that our heart belongs to fire and our kidneys belong to water. They are a relationship of yin and yang. The heart is god and the kidney is essence. Heart and kidney should be harmonious, that is, heart is above and kidney is below, that is, fire is above and water is below. Heart fire is like the sun, kidney water is like the sea. The heat of fire must come down to warm the earth so that everything can grow. Kidney water is like rain. It needs to steam up, and then it rains to lower the heat in the sky. It's called incompatibility. This is also the concept of the intersection of yin and yang. The disharmony between heart and kidney means that heart fire is better than heart fire, but kidney water can't help heart and restrict heart fire. This is the deficiency of kidney Yang Qi, which is not enough for transpiration and gasification to make kidney water soar. This can easily cause insomnia.
The recipe I shared with you today is called Jiaotai Pill. There are only two simple Chinese medicines in the prescription, cinnamon and coptis.
Let's take a look at cinnamon, which is a mild medicinal material. This product can tonify fire, help yang, induce fire to return to yuan, dispel cold and relieve pain. At the same time, it also enters the heart and kidney meridian, which can lead the kidney water upward, thus clearing the heart fire.
As we all know, this kind of Rhizoma Coptidis is a bitter medicinal material, which enters the heart meridian and is a good product for purging heart fire. It has a good curative effect on people with dizziness, irritability and insomnia caused by excessive heart fire.
The combination of the two medicines, one for tonifying and one for purging, is a simple prescription for patients with excessive heart fire, heart-kidney disharmony, palpitation and restlessness, or insomnia at night and sores on the mouth and tongue. If you have such people around you, you can collect them and seek TCM syndrome differentiation.
