Incense, the origin of aromatherapy, is proven to help the mind be peaceful and de-stressed. Stress has now been found to attack the immune system thus linking it to diseases like cancer. Quality incense immediately creates a spiritual atmosphere because it surcharges the ether with positive energy (earth, fire) dispersing subtle negative influences. …thus it is good for meditation and inner peace.
In South Arabia Incense got a strong social function. It is often burned after a social gathering. If the incense starts to smolder is the moment of parting arrived.
