Salvia Divinorum was discovered by the Mazatec indians. The shamans of the Mazatec tribe used this holy medicine to induce a trance. In this trance they could travel through the unconsciousness of the patient to find the source of a disease.
The active compounds of salvia divinorum are salvinorin A en salvinorin B. The main compound salvinorin A is currently the strongest isolated hallucinogenic substance known.
You cannot compare Salvia with other hallucinogenic plants like magic mushrooms and cacti, is has itīs own unique effect. Salvia causes only a short trip, 20 minutes to 1 hour. After this you return to reality quickly.
During the trip several states can occur: 2-dimensional hallucinations, out of body experiences, becoming a object, travelling back in time, being in more places at once and uncontrolled laughing.
The Mazatec indians used two methods of consuming salvia: chew for a long time and then swallow down the leaves, or dissolve the leaves partially in water and drink it. However, both methods are not very tasteful.
When you are new to salvia, start of with only a very small amount to test your sensitivity. The effect of salvia are different for each person and can for some be very overwhelming.
