Salvia divinorum is an herb that is closely related to mint, oregano and basil. But unlike its relatives, salvia produces salvinorin A, which is a psychoactive diterpene. When chewed, smoked or drunk as a tea, salvia produces a mild psychoactive effect. It is also traditionally used to aid in meditation. Before you grow, harvest or prepare Salvia divinorum, make sure that it is legal to grow and use in your state.
Harvest 1-year-old or older Salvia divinorum leaves. Pinch off the largest leaves at their base, but leave the tissue just below the stem that it is responsible for growing new leaves. You can also wait until the leaves die and fall off to harvest them.
Wash the leaves with water. If you have used pesticides on the your salvia plants, rub them with vinegar for a few seconds before rinsing to help remove any chemical residue.
Roll anywhere from eight to 28 fresh, washed salvia leaves into a cylinder or ball to prepare it for chewing. Chew the leaves periodically so the juice gathers in your mouth, but do not swallow. Spit the leaves and juice out after chewing for 30 minutes.
Dry the salvia leaves by spreading them out in an oven-safe dish and placing them on the middle rack of your oven. Set the oven's temperature to 150 degrees F and leave them to dry until they are brittle enough to be crushed by your hand.
Place the leaves in a pipe or waterpipe over a filter. Use a torch-flame lighter to light the Salvia divinorum. Inhale as much smoke as you can in one inhalation. Hold the smoke in for 20 seconds, then exhale slowly.
Bring 1 cup of water to a boil. Add 8 ounces (or more for stronger tea) of dried salvia leaves (in an infuser if possible; if not, you will have to strain the leaves later) and leave them to boil for three minutes. Take the pot off of the fire and leave the leaves to steep for five minutes. Add milk or honey to this bitter tea before drinking.
