Acoraceae
Reviewed by The Sarv Health Team · Our editorial process

Calamus rhizome is traditionally used to restore the throat and voice, especially among singers. In Chinese medicine, a related species is known to improve cognitive function by removing stagnant phlegm and has been used for head trauma patients to reduce cognitive fogginess. While there's no research on calamus and dementia, it might be worth exploring. Calamus also supports the gastrointestinal tract, being particularly effective for flatulence, digestive complaints, and a condition called water brash. However, very high doses can lead to hallucinogenic effects.
Medicinal Uses
Calamus rhizome, with its trachea-resembling appearance, has traditionally been favored by singers and performers to restore the throat and voice, drawing on the doctrine of signatures which suggests that herbs resemble the body parts they are effective in treating.
In terms of cognitive enhancement, the related species Acorus gramineus is recognized in Chinese medicine for its ability to clear the mind and improve cognitive function by eliminating stagnant phlegm-like substances. Calamus has been applied in clinical settings to assist patients with head trauma, reducing mental fog and aiding concentration. Although no formal studies have linked calamus to dementia treatment, its potential benefits in this area merit further exploration.
Calamus is also known for its support of the gastrointestinal tract, where its high volatile oil content proves beneficial for digestive issues such as flatulence and water brash�a condition where an acrid liquid is regurgitated into the mouth. Chewing a small piece of calamus root can quickly alleviate these symptoms.
However, it's important to note that very high doses of calamus have been reported to cause hallucinogenic effects, indicating the need for caution in its use.
