||By division of rhizomes in early spring.
||Plants are lifted at any time, except during the flowering period. The required amount of rhizome is cut and the remainder replanted. The rhizome may be dried for use in decoctions, distilled for oil (A. calamus), or used fresh for tinctures, liquid extracts, pastes, and powders.

To treat ulcers, rheumatism, toothache, pain syndrome, gastrointestinal disorders, gum disease, tonsilitis, and fungal infections.
|Evidence of Benefit:
||Acorus is an antioxidant that has special effects on the central nervous system. It is used by the Akha people of Thailand for stomachache. The Chinese use it for vomiting, diarrhea, abdominal pain, and dysentery. This herb eliminates phlegm and tranquilizes the mind, and has been used to treat amnesia, heart palpitations, insomnia, tinnitus, chronic bronchitis, and bronchial asthma.
Benefits of acorus for specific health conditions include the following:
- Drug Withdrawal: Acorus affects the brain during withdrawal from cocaine, heroin, and morphine. During the first one to ten days of withdrawal, addicts experience intense drug cravings, nausea and vomiting. Acorus can blunt gastric upset during the acute phase of drug withdrawal (although it has no effect on the cravings themselves) through its ability to prevent the secretion of the inflammatory chemical histimine.
- Seizure Disorders: Acorus is used to treat a broad range of brain conditions. It works by protecting brain tissue from toxic free radicals, which are released in the presence of excess oxygen. When the flow of oxygen is restored to previously oxygen-deprived brain cells, these cells are temporarily unable to use all the oxygen available to them. The oxygen escapes the biochemical pathway that usually control it and free-radical damage results. The resulting tissue damage in the brain can lead to memory loss or seizures. Acorus helps prevent the formation of free-radicals of oxygen and the resulting brain tissue damage. It is most effective when taken before circulation is restored, that is, in the first few days to a month after head injury or stroke.
|Consideration for Use:
||Acorus is most commonly supplied by practitioners of traditional Chinese medicine (TCM). It is usually sold in the United States as Chang Pu, or Shi Chang Pu, in the form of powder, teas, and tinctures.
The herb's American relative calamus contains the potentially cancer-causing chemical beta-asarone, which has caused it to be banned for use in the United States. Although the form of Acorus used in TCM is legal in the United States, it is restricted in Canada. Many other countries ban the use of both acorus and calamus in herbal medicine. Acorus should never be used without professional supervision.
|Possible Side Effects:
||No side effects or health hazards are known when calamus is taken in designated therapeutic dosages. However, rats receiving calamus oil over an extended period of time developed malignant tumors; therefore, long-term use of calamus should probably be avoided.
