Item# TNHRMA030M 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 3000 mg of pure harmine in 1 liquid ounce (30 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 harmine. Each drop contains approximately 3.5 mg of harmine. Harmine is one of the main alkaloids found in Peganum harmala and 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 Peganum harmala is harmaline. Virtually all the harmaline has been removed from this product. Our harmine freebase is extracted from Peganum harmala 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, harmine glows bright blue in UV light and is used to make water paint for black light special effects. Recommended Usage: Harmine is for use as a coloring additive which fluoresces in UV light. When highly diluted, harmine is nearly colorless but still fluoresces brightly in black light. Harmine is great for creating fluorescent water colors used in black light art projects. For use as a fluorescent coloring additive dissolve 20 drops in 10 ml of water. If not dilute enough, fluorescence is hindered. Once diluted, it may be adding to water based paints, water based inks, etc. Harmine may also be used as a fluorescent pH indicator (as the pH increases the fluorescence of harmine decreases). 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 harmine is extracted from organic Peganum harmala seeds using 100% safe food grade ingredients, harmine 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 harmine in liquid form sold for use as a 100% natural fluorescent coloring additive for art projects.
