Stomach Disorders

Calamus gives relief to heavy stomach by relieving f1atuJenc.e, colic and increasing appetite. The burnt root mixed with some bland oil such as refined coconut oil or a poultice of the root may be applied over the abdomen in treatment.

Diarrhoea and Dysentery

The drug is a time-tested remedy and is an ingredient in Ayurvedic medicines for chronic diarrhoea. It is also effective in chronic dysentery, due to the presence of tannins. Its infusion can be given to children suffering from these ailments.


Calamus is highly beneficial in the treatment of asthma; it removes catarrhal matter and phlegm from the bronchial tubes. About 65 centigrams of the herb is taken every 2 or 3 hours in this condition.

Common Cold

The herb is also useful in treating common cold. A small piece of the rhizome is roasted and powdered. A pinch of this powder taken with honey provides great relief. For infants, the paste of calamus mixed in breast milk is touched on the baby's tongue. Another convenient method of giving the medicine to infants is to apply a little paste on the mother's nipples.

Whooping Cough

The powder of the roasted herb is an effective home remedy for children suffering from whooping cough. A pinch of this powder can be given with honey. Being antispasmodic, it prevents the severe bouts of coughing. For smaller children, the dose must be proportionately smaller.

Intestinal Worms

Calamus is effective in expelling intestinal worms. The powdered root is taken for this purpose.

Mouth Disorders


The herb is useful in treating mouth ulcers, coating on tongue and rawness, that is, inflammation of the skin. A small piece of the herb should be rubbed on the tongue to obtain relief.
