How to distinguish natural fragrance from chemical fragrance in health preservation?

Natural fragrance, showing the natural color of natural raw materials, will not fade when soaked in water or alcohol. Chemical spices are mostly colored with chemical dyes, showing red, yellow, green, purple, black, gold and other colors. Soaking in water or alcohol will fade.

Natural fragrance, you need to smell it at close range before lighting, so there is a faint fragrance of grass, woody and medicinal materials. Chemical spices give off a strong fragrance long before they are lit; It smells stronger and even pungent when approaching.

Natural fragrance, light specific gravity and low density. After burning 100g incense, the weight of incense ash should not exceed 6g. And under the same weight, the volume and quantity of pure natural incense are more than that of chemical incense 15%-25%. Chemical essence, adding a lot of wood powder, stone powder and chemical glue containing impurities. Therefore, the specific gravity is heavier, the density is higher, and the hand feel is reduced. After burning100g incense, the weight of incense ashes will far exceed 6g, even as high as 30g.

Natural fragrance, long-term exposure to the sun, not easy to taste and fade. Chemical fragrance, after exposure to the sun for two or three hours, the fragrance obviously fades, accompanied by fading. After a day or two in the sun, there is basically no fragrance. After ignition, the smoke is pungent or turns into another taste.

Natural fragrance, fragrant ash fluffy flake, flake off when falling. The whole thing looks like a lotus flower blooming gradually. Chemical incense, incense ash column smooth and straight, not easy to fall off, and often accompanied by the phenomenon of incense ash volume shrinkage. After the incense ashes fall, most of them can remain intact and are not easy to disperse.

Natural incense and incense ashes will not feel obvious temperature even if they fall close to their hands. Chemical incense is usually added with combustion improver (KNO3), so the temperature of incense ash is very high, and it is easy to burn the skin when it falls far away from the hand.

Natural incense, the incense ashes on the ignition point, will fly all over the sky when blown, like snowflakes, and smaller incense ashes can float in the air for a long time. Chemical incense, burning incense ashes, is difficult to blow with your mouth. After barely blowing off, pieces of incense ashes fell directly to the ground.

Natural fragrance, fresh and natural fragrance, even if it is lit for a long time, it will not cause physical discomfort. Chemical fragrance, mixed with many irritating chemical raw materials, makes people feel dizzy, tired and breathless for a long time, accompanied by slight dyskinesia.

Natural fragrance does not add any other materials except natural fragrance and plant gum, so the similarity between lit natural raw materials and their corresponding fragrance should be higher than 80%. Chemical incense uses a lot of sawdust, chemical glue, chemical synthetic essence, sesame oil, stone powder, chemical dyes and combustion improvers. Smokeless incense will also add industrial toner. Roll money incense (hook furnace incense) and add glass glue. Golden elephant will also add heavy metal toner; Flower fragrance series, mostly made of chemical synthetic essence ... so the smell of chemical fragrance after lighting is very similar or even irrelevant to the product name marked on the package.
