Gynostemma has the effects of benefiting qi and strengthening the spleen (regulating the qi of the spleen and stomach), resolving phlegm and relieving cough (removing phlegm evils and stopping coughing), and nourishing the heart and tranquilizing the mind (stabilizing the mind by nourishing the heart). It is mainly used for treating weakness after illness, qi deficiency and yin injury (damage to yang qi and yin fluid), cough and asthma, palpitation (rapid heartbeat, often accompanied by panic) and insomnia. Gynostemma has a bitter, slightly sweet flavor and is cool in nature. It belongs to the lung, spleen and kidney meridians, and is often used in the treatment of post-disease weakness, qi deficiency and yin injury, lung heat and phlegm (excessive phlegm caused by heat in the lungs), as well as chronic bronchitis, infectious hepatitis, nephritis, leukopenia, hyperlipidemia, and so on. Gynostemma is sweet and cold, and is contraindicated for those with spleen and stomach deficiency (weak and cold spleen and stomach). Its adverse reactions have not been found in clinical use. It should not be taken in large quantities for a long period of time, and cold foods should not be consumed during the period of taking it. If you need to use the drug, you need to use it under the advice of a doctor, do not use it blindly on your own, so as not to cause discomfort to the body.
