Juniperus chinensis has the effects of clearing heat and resolving phlegm, softening and dispersing knots (softening and dispersing hard lumps), and moistening the intestines and laxatives. It can be used to treat lung-heat cough; chest paralysis (chest tightness and pain); thirst; constipation; carbuncle and sores. Juniperus communis, also known as Piper guajava, is the mature fruit of Juniperus communis, family Cucurbitaceae. It is sweet, bitter and cold in nature, and enters the lung, stomach and large intestine meridians. It is mainly used for treating lung-heat cough, phlegm with yellowish consistency, chest pain, breast redness, swelling and heat pain, coughing and vomiting fishy pus and phlegm, as well as dry stool or constipation. It is bitter and cold in nature, easily injuring the spleen and stomach, and should be used with caution by people with cold spleen and stomach (spleen and stomach weakness and cold). In addition, Juniperus communis root can also be used as medicine. Juniperus communis root, also known as smallpox pollen, has the efficacy of clearing away heat and fire (removing heat and fire from the body), generating fluids and quenching thirst (promoting the production of fluids to quench thirst), and subduing swelling and discharging pus (eliminating pus and swelling and discharging pus). It is contraindicated in cases of coldness in the spleen and stomach with slippery stools. Note that neither Juniperus chinensis nor Juniperus chinensis root should be used with aconite herbs, and the adverse effects are not known. The application of the drug should be guided by a medical professional and should not be used on one’s own to avoid delaying the condition.
