Item# TNTHHT007M THIS IS OUR NEW GLYCERITE TINCTURE FORMULA! As requested, we no longer use vinegar as a preservative in this product, and now use glycerin as a preservative. Our new glycerite tincture contains 740 mg of pure tetrahydroharmine in 2 liquid drams (7.4 ml). The liquid base is formulated using food grade vegetable glycerin and purified drinking water. Each 1 ml dropper full (approximately 28 drops) contains 100 mg of tetrahydroharmine. Each drop contains approximately 3.5 mg of tetrahydroharmine. Tetrahydroharmine is one of the main alkaloids found in Banisteriopsis caapi. It glows in black light (UV light) and is useful for creating psychedelic artwork meant to be viewed in black light. The other major alkaloid found in Banisteriopsis caapi is harmine with traces of harmaline. All the harmine and harmaline has been removed from this product. Our tetrahydroharmine freebase is extracted from Banisteriopsis caapi using a 100% food grade non-toxic extraction procedure that is environmentally friendly. We use only pure drinking water and non-toxic food grade ingredients suitable for cooking. Description: when diluted many times in acidic water, tetrahydroharmine glows bright blue in UV light and is used to make water paint for black light special effects. Recommended Usage: Tetrahydroharmine is for use as a coloring additive which fluoresces in UV light. When highly diluted, tetrahydroharmine is nearly colorless but still fluoresces brightly in black light. Tetrahydroharmine is great for creating fluorescent water colors used in black light art projects. For use as a fluorescent coloring additive dissolve 20 drops completely in 10 ml or more of water. If not dilute enough, fluorescence is hindered. Once diluted, it may be added to water based paints, water based inks, etc. Storage: keep in a dark cool air tight container free from moisture. If storing for extended periods of time, it should be kept in the refrigerator. Keep out of reach of children. WARNING: although our tetrahydroharmine is extracted from Banisteriopsis caapi using 100% safe food grade ingredients, tetrahydroharmine can be toxic when ingested in sufficient quantities. Do not use as a food additive or food coloring. DO NOT INGEST. KEEP OUT OF REACH OF CHILDREN. 1 factory sealed dropper bottle contains 3 grams of pure tetrahydroharmine in liquid form sold for use as a 100% natural fluorescent coloring additive for art projects.
