HerbEra Quinine Tincture, Herbal Dietary Supplement for Immune System Support, Cinchona (Cinchona officinalis) Dried Bark Extract, Natural, Alcohol Tincture, Drops 2x4 oz

I like tonic water which has 80 ppm quinine in sweet soda. The quinine has a nice bitter taste. Also, quinine has the cool property that it glows (fluoresces) under a black light. See top of image, where I compare plain water to tonic water. The tonic glows brightly in aqua blue, but the water doesn't glow. Next I took _one_whole_ounce_ of Herbera "Quinine A120" and dumped it in the water. The water turns brownish, but doesn't show any evidence of glowing. That is, much less quinine than is present in tonic water. I could have told you this, because even straight from the bottle, Herbera Quinine A120 has no bitter taste at all. I've done this experiment with both the alcohol-based and water-based product with same results. But don't just trust me. Take a drink of tonic water and then a drink from the Herbera extract. You will find that the tonic is much more bitter (has more quinine per ounce) than straight from the bottle. Now, I went to the trouble of making these tests because I contacted Herbera several times regarding the water/alcohol based extracts. I asked them to taste the extract themselves and compare to tonic water. They refused. Instead, they said they don't know how much quinine is in there, they just make a slurry of the Chincona tree bark. But not all Chincona bark has quinine in real life, only a small layer of the inner bark has quinine. So grinding up Chincona bark does not guarantee you'll get any quinine at all. This is what Herbera has done. Putting Quinine on the label of this stuff is a pure lie -- false advertising.
