Calamus works to clear toxins of both majjavaha (nerve channels) srotas and manovaha (mental channels) srotas. This results in better circulation and oxygen to the deep tissue areas of the brain and central nervous system. It is a brain tonic that promotes better concentration, clarity, self-awareness, memory, and intelligence. It improves cognitive skills and reaction time by synchronizing the two cortexes of the brain.
The Sanskrit meaning of the word Vacha is to increase the power of speech. It improves speech so that one can express internal thoughts more clearly. It reduces mental stagnation by stimulating the channel faculties of the brain. It allows better communication to thoughts and feelings. It helps to expand self-awareness in relationship to others.
Calamus steadies the mind of disturbances to stress, headache, dizziness, lethargy, fear, seizures, shock, convulsion, mania, and mental congestion. It pacifies the negative tendencies of sadness, grief, irritation, mental stress, anxiety, hysteria, and depression.
