Because borneol has processed products, some drug dealers add sugar and sand to borneol to gain improper benefits, so attention should be paid to identification when using it.
The appearance of real borneol is transparent or translucent flaky crystals with different sizes. Natural borneol is white or grayish brown, while machine-made borneol is as white as snow, like plum blossom, with ice-like cracks on the surface and crisp texture, which is easy to turn into white powder after being twisted by hand. It smells particularly fragrant, tastes cold and melts slowly when chewed.
Physical detection: after sublimation, a small amount of borneol was observed under the microscope, and its crystal was rod-shaped or polygonal. There is no black smoke when natural borneol burns, and there is a little black smoke after machine-made borneol burns.
Pseudoborneol can be seen as sand or granular crystals; Hand twisting is not easy to break, and there are slag particles. The smell is slightly fragrant, the taste is cool and sweet, and it cannot be completely dissolved. There is residual sand, etc. Observe rare rod-shaped crystals with a microscope.
Borneolum can be eaten directly. The common causes of sore throat are virus infection, allergic diseases, swelling and pain caused by excessive internal heat, etc. This kind of sore throat can be properly eaten with borneol, which can calm the laryngeal mucosa and relieve the symptoms.
Note: Borneolum Syntheticum is toxic and should not be taken in large quantities, especially synthetic Borneolum Syntheticum, which is toxic and should not be taken for a long time.
The side effect of borneol is mainly to stimulate the gastrointestinal tract. If the dosage is too large, it will cause gastrointestinal nausea, vomiting and abdominal pain. In addition, it will also cause problems in consciousness, such as loss of consciousness, convulsions, etc., which will lead to respiratory failure in severe cases.
