In Ayurveda it is believed that the nose is the direct passage to the brain. Nasya is an ancient method of dropping a substance into the nose and inhaled in order to lubricate the passages and make way for chi or prana (life force) to enter the head and body. Substances can be medicated oils / juices / and powders which stimulate the vital centres of brain.
When we administer herbal oils (nasya) it helps clean toxins that accumulate in upper body (sinus, throat, nose, head areas). Certain oils sooth and protect the delicate mucus membranes, also receiving tension in the head and relief stress. This can balance VPK. It was also noted that nasya can sooth the voice making it more attractive.
Certain people use nasya for hair fall, helps eyesight and promote mental clarity.
Please consult an Ayurvedic Practitioner to see if this is a suitable daily practice that can be incorporated into your life.
