Overview
Calamus Root (Vacha, meaning literally "speaking"—the power of the word, of intelligence or self-expression that this herb stimulates) is a rejuvenative for the brain and nervous system. Its rasa is pungent, bitter and astringent, with a heating virya and pungent vipaka. It pacifies Vata primarily and Kapha secondarily, while increasing Pitta.
Calamus purifies and revitalizes the brain and nervous system, clearing the subtle channels of toxins and obstructions. It promotes cerebral circulation, increases sensitivity, sharpens memory and enhances awareness. It is sattvic and one of the best herbs for the mind, along with brahmi (gotu kola), with which it can be combined. It also helps transmute sexual energy and feeds kundalini.
Acting on the plasma, muscle, fat, marrow and nerve, and reproductive tissues through the nervous, respiratory, digestive, circulatory and reproductive systems, calamus is indicated for colds, cough, asthma, sinus headaches, sinusitis, arthritis, epilepsy, shock, coma, loss of memory, deafness, hysteria and neuralgia. It can be applied externally as a paste on the forehead for headaches. Note: calamus is currently under FDA restrictions and not recommended for internal usage in the US. Preparation forms include decoction, milk decoction, powder (250 to 500 mg) and paste.

Properties and Uses
Calamus root is hot and penetrating and is used as an expectorant. It is also an emetic.
As a powder, it may be taken into the nose like snuff to relieve sinus congestion, common cold or sinus headache. It may create sneezing which will cleanse the respiratory tract.
According to Ayurveda, calamus is anticonvulsive. It is used for epileptic seizures. It acts on the higher cerebral functions and brain tissue to help expand and bring clarity to the consciousness.
Calamus root is the best antidote for the ill effects of marijuana. Marijuana is toxic to the liver and the brain cells; however, if one smokes a pinch of calamus root powder with the marijuana, this herb will completely neutralize the toxic side effects of the drug. The side effects of all psychedelics can be neutralized by calamus root.
Calamus root is also used to improve the memory. In the morning and evening, take a pinch of the powdered root with one-fourth to one-half teaspoonful of honey.
If one drinks two to three glasses of calamus root tea, it will cause vomiting. This action is therapeutic for chronic cough and asthma. Calamus root is also a broncho-dilator and acts as a chest decongestant.
The medicated oil of calamus root may be used for nasal administration and also externally for massages to relieve vata and kapha disorders. Massaging with this oil will relax tense and sore muscles and create a feeling of freshness.
