How to distinguish the quality of fragrance?
We call fragrances made from natural spices "natural fragrances", fragrances with artificially synthesized spices "chemical fragrances", or perhaps "fragrance crafts". Chemical fragrance only has the appearance of fragrance and imitations of aroma, but lacks the connotation and efficacy of natural fragrance.
appearance
The appearance of natural fragrance is generally a natural light brown color (according to research, this is also inconsistent, and many chemical fragrances do not add color), which is the color created by the crushing and destruction of natural plants. If natural fragrance is dyed with color, it usually does not last for a long time, and the color will fade away after about half a year, becoming colorful and not attractive. Therefore, natural fragrance does not have beautiful colors. Those with colors are definitely not natural fragrance, but those without colors are definitely natural fragrance. It's not certain that we need to compare more points. Natural fragrance pursues the characteristic of "fragrance nourishing nature", therefore, its appearance looks relatively simple and not very smooth; And the appearance of chemical fragrance is exquisite and gorgeous, with a smooth surface and beautiful colors.

flavor

From the taste, when not lit, the natural fragrance does not have a very fragrant taste. Only by getting very close to the nose can one smell the faint medicinal fragrance emitted by pure natural plants. After being lit, the aroma will be very prominent and pleasant to smell. The fragrance is fresh and refreshing, and there will be no dizziness after long-term use; The fragrance is mellow, with a moderate intensity, and it doesn't feel pungent even after taking a deep breath; Natural fragrance often exudes a slight astringency and medicinal flavor within its aroma. Natural fragrance can invigorate the mind and provide a sense of pleasure, but it does not make people feel restless or agitated; Can make people relax both physically and mentally, and have a calm and beautiful mood; It nourishes the body and mind, making people willing to get close to it.
Chemical fragrances, on the other hand, have a strong and pungent aroma when not lit. Some can be smelled from a distance, but when lit, they become even more pungent and irritating to the nose and eyes. Although these chemical fragrances are only a mixture of artificial fragrances, flammable substances, and combustion aids, they have a similar aroma to natural fragrances. However, after burning, they do not have their health promoting function, and their toxic side effects can be significant. The formaldehyde and benzene released are carcinogens. Some shops selling chemical fragrances can smell the fragrance even before entering.
Fragrant ash
The natural fragrance ash is fundamentally gray and grayish white, while the chemical fragrance ash contains many black substances in the gray, which is the combustion enhancer lime.
The ash of natural fragrance is not easy to scatter, and if it is the ash of string fragrance, it can be preserved for at least 1 centimeter; The chemical fragrance ash is usually more scattered and will fall off after leaving for a short time. I'm not entirely sure about this, we need to combine it with several other points to make a judgment.
The natural fragrance of fragrant ash hits your hand, and what you smell is the scent of burnt grass ash from plants; The chemical scented ash still has a residual fragrance on the hand, and for people with sensitive skin, this area of skin may still turn a little red, mainly due to the influence of chemical synthetic agents on the skin.
The color of smoke
The smoke produced by natural fragrance is fundamentally blue and white, with a uniform color from the ignition point onwards; The smoke with chemical fragrance is blue-green, and the nearby ignition point is black.
psychology
Natural spices often provide subtle physical and mental experiences such as pleasure and emotion, while chemical spices have almost no such effect. The barrier that chemical spices have always been unable to overcome is that they have their own taste but no aroma, and their own form but no form. As the ancients said, the fragrance is like a miraculous medicine, which can cure illnesses, open one's mind, clear the passage, and realize the wonders. It is not an empty promise.
