The fruit of the neem tree, neem seed, is known to expel roundworms from the body, move qi and relieve pain (by regulating the body’s qi), and drain heat from the liver. Neem seed is the dried, ripe fruit of the neem tree of the neem family, bitter in flavor, cold in nature, slightly toxic, and belongs to the liver, small intestine, and bladder meridians. The functions of neem seed are to drain heat from the liver, move qi, relieve pain and kill worms. The drug is commonly used clinically for the treatment of liver depression and fire (liver qi is impassable leading to the production of fire and heat), chest and hypochondrium (a collective term for the chest and ribcage area), epigastric distension and pain, hernia pain, and abdominal pain caused by worms. The medicine can be taken internally or used externally in a powdered form to mix and apply. Neem should be used with caution in pregnant women. When discomfort occurs, you should seek medical attention and use the drug under the guidance of a doctor, not self-medication.
