Patient: "Pharmacist, is Sichuan root tea mixed with tea to be taken?" Pharmacist: "Yes, Sichuan yam tea needs to be taken with clear tea after meals." "The clear tea here is for medicinal introduction.
So, what exactly is a drug introduction? What are the effects of drug introduction? Certain drugs or foods, formulated in the prescription, have a special direction or effect on a certain part of the body or certain conditions, called drug introduction. "Medical Ladder and Medicine Introduction" says: "Soup has a citation, like a boat has a sword." The ancients used soup, which had to be quoted [1]. ”
The effects of drug introduction can be roughly divided into the following categories:
Introduction to the scriptures: Drug introduction can make the drug directly to the hospital and give full play to the therapeutic effect. For example, in the gentian diarrhea liver soup, chai hu is used as a guide, and various drugs are introduced into the liver and gallbladder to enhance the efficacy of the stripe liver qi. Liuwei Dihuang Pill is taken with light salt water as a guide, and taking salty can introduce medicine into the kidneys, and better play the role of tonifying the kidneys.
Enhanced efficacy: Drug introduction can enhance efficacy. If you treat wind fever and cold and high fever with reed root and bamboo leaves as medicine, its heat-clearing and fever-reducing effect will be stronger. When treating cold and cold, when the wind is cold, ginger and green onion white are used as medicine, because the onion and ginger taste spicy and warm, can spread the wind chill, strengthen the effect of sweating and anti-table. The use of rush grass as a guide in the eight positive scatters can not only conduct heat downwards and pass the trick, but also enhance the effect of dehumidification.
Detoxification effect: For example, the poison of raw half summer and raw southern star is greater, and the use of ginger as a medicinal introduction can reduce its toxicity and reduce its side effects. Licorice is used to reduce its toxicity.
Tempering medicinal properties: Some drugs have a strong effect, and adding some drugs can alleviate the medicinal properties and protect the righteous qi. For example, the cold diaphragm scatters white honey as a medicinal introduction, which can not only slow down the sex of the yellow and yellow nitrate, but also store stomach jin and moisten the knot. The jujube diarrhea lung soup is introduced by jujube, which can not only alleviate the intensity of the amaranth, but also relieve the lungs without hurting the lungs.
Protect the spleen and stomach: Some drugs are easy to stimulate the gastrointestinal tract, so that the digestion and absorption function is reduced or gastrointestinal reactions occur, and adding some drugs can protect the spleen and stomach. Such as the white tiger soup that clears the heat and relieves the heat, the bitter cold defeats the stomach, and the addition of japonica rice as a medicinal introduction can not only benefit the stomach and protect the body, but also prevent the bias of the great cold injury. Three yellow gypsum soup has adverse irritation to the stomach, and ginger and jujube are added as medicinal introductions to alleviate its stimulation of the stomach [3].
Taste correction effect: Some drugs are heavy and difficult to swallow, and can be used to reduce odor. If rock sugar is added to the heat clearing agent, caramel is added to the warm supplement, honey is added to the moisturizing agent, sugarcane juice is added to the cooling agent, and brown sugar is added to the cold and blood activating agent, which can not only correct the bitter taste in the decoction, easy to take, but also enhance the medicinal effect.
As for the Sichuan Root Tea Dispensing that the patient asked, it comes from the Song Dynasty's "Taiping Huimin and Pharmacy Bureau Fang", which is served with tea. This party is composed of Sichuan root, Bai Zhi, Qiang Huo, Fine Spice, Windproof, Thorn Mustard, thin licorice, and is used to treat headaches caused by external wind and evil. In this formula, clear tea as a medicinal introduction, has the effect of clearing the leader, awakening the spirit, can be introduced to the sutra, directly to the hospital.
It should be noted that the introduction of drugs has its own merits and should be "individualized administration".
For example, when you see a cold, you will take onions and ginger as a guide, and if you encounter evidence of wind and heat, that is, if you hold a salary to fight a fire, it will aggravate the condition. Another example is the beginning of pediatric sha acne, in the south there are in the epidermal drugs with the tip of the bamboo shoot as a guide, to help publish, in order to promote the use of acne pulp. As a medicinal introduction, it can be used in a small amount of decoction, and if it is used too much, it will hurt the gas. It should be noted that the acne rash develops into grouting, there is a cracking wet itch, and when the acne rash gradually closes, the tip of the bamboo shoot is avoided.
