Traditional chinese medicine Sini Tang Main efficacy
Sini Tang is mainly used to treat cold syndrome caused by deficiency of Yang in the heart and kidneys. Symptoms include coldness and numbness of the limbs, chills and curling up, neurasthenia and drowsiness, pale complexion, abdominal pain and diarrhea, vomiting without thirst, white and slippery tongue coating, and weak pulse.
The pathogenesis is deficiency of heart and kidney yang, excess of yin and cold inside the body, inability of yang qi to warm the extremities of the whole body, resulting in cold limbs, aversion to cold and lying down; inability to stimulate blood circulation, resulting in a weak pulse.
Indications
The symptoms that Sini Tang is suitable for include changes in pulse and tongue. In terms of pulse, deep and thin pulses are common; in terms of tongue, green tongue coating, purple tongue tip, and thin white tongue coating are common. These changes in pulse and tongue usually indicate that the body's yang is insufficient and yin and cold are excessive.
Pulse: Deep pulse, thin pulse

Most of these pains are caused by the cold evil in the body blocking the meridians, resulting in poor circulation of qi and blood.
In addition to pain, Sini Tang can also relieve a variety of systemic symptoms. These symptoms include frequent fatigue and sleepiness, chills, coldness in the abdomen, chills, cold hands and feet, cold head, depression, diarrhea, coldness in the genitals, coughing, hiccups, shortness of breath, irritability, frequent urination and diarrhea accompanied by indigestion. These symptoms are usually caused by insufficient Yang Qi in the body and excessive Yin and cold, leading to systemic dysfunction.

Prescription explanation and efficacy
Aconite: Aconite is very pungent and hot, and is the most important product for replenishing the innate life gate true fire. It can pass through the twelve meridians, quickly reach the inside and outside to warm the kidneys and strengthen yang, dispel cold and rescue adverse conditions. It has the effect of exciting nerves, stimulating cells, increasing body temperature, and strengthening all functions of the body.
Dried ginger: Dried ginger is also a hot medicine, warming the yang of the middle burner and removing the internal cold, helping aconite to raise yang, expelling yin and returning yang, and complementing aconite. Volume 10 of Ben Jing Shu Zheng says: "Aconite moves downward, and dried ginger guards the middle. If there is ginger but no aconite, it is difficult to achieve the effect of cutting down the general and seizing the flag. If there is aconite but no ginger, it is difficult to achieve the effect of fortifying the wall." Aconite and ginger can be used together to warm and strengthen the yang of the spleen and kidney, dispel cold and rescue adverse conditions.
Roasted Licorice: Since the two herbs of aconite and dried ginger are too warm and dry, they may damage the Yin fluid, so roasted licorice is used to harmonize the other herbs to reduce the disadvantages of aconite and ginger being too pungent and hot and damaging the Yin fluid. Licorice can detoxify and also alleviate its overly pungent and hot nature.
