[Prescription name] Acorus calamus (wash, dry, and slice for use), fresh calamus, fresh Acorus calamus (fresh ones can be used as needed, suitable for phlegm-heat coma.)
[General dosage and usage] One to three qian of dried ones, three to five qian of fresh ones, decocted and taken.
[Comments] 1. Acorus calamus, borneol, and musk are all aromatic and rejuvenating medicines. However, although the aromatic fragrance of borneol and musk is small, their rejuvenating and resuscitating effects are also strong; Acorus calamus, through its aromatic and damp-removing effect, has the effect of resolving phlegm and clearing the lungs, rejuvenating the orifices and unblocking, so it is suitable for symptoms such as phlegm and turbidity blocking the orifices, unclear consciousness, and difficulty in speech, but its rejuvenating and resuscitating effects are weak.
2. In addition, Acorus calamus can also refresh the mind and strengthen the stomach, which is its specialty. Therefore, adding Acorus calamus to the prescription for tranquilizing the mind can often enhance the efficacy, such as the patent medicine Anshen Buxin Pill (Dashengdi, Danshen, Schisandra, Shouwu Teng, Eclipta prostrata, Acorus calamus, Albizzia julibrissin, Ligustrum lucidum, Cuscuta australis, Mother of Pearl).
3. According to ancient literature, the root of this product is thin and dense, and nine nodes per inch is good, so the prescription often writes nine-node Acorus calamus, which is believed to have better efficacy. However, the raw material of nine-node Acorus calamus used in the market now is the stem of Altai Anemone (Chrysanthemum-shaped Double Bottle Plum) of the Gentianaceae family, which is two different plants from Acorus calamus and should not be mixed, so the name of nine-node Acorus calamus is not used in the above prescription.
