What does the fragrant stone do?

The air is fresh, fragrant and deodorized, healthy in body and mind, mildew-proof and insect-repellent, moisture-absorbing and moisture-proof, with in addition to formaldehyde flavor.

Stones in nature are inorganic substances, and anyone who has studied chemistry knows that inorganic substances have no fragrance. So how did this fragrance come into being? Geologists have found some rocks in the lush mountains, which give off different degrees of fragrance. Through infrared spectrum analysis, it is found that these rocks contain some organic components, and the aroma with more organic matter is strong, while the aroma with less organic matter is weak. Studies have confirmed that this fragrance is produced after substances with spices have invaded rocks for a long time. This shows that the distribution of fragrance is not only related to the species of flowers and plants around the rock, but also depends on the adsorption ability of the rock to organic matter. Through the detection of some rocks, it is found that this yellow-green serpentine has a strong adsorption capacity for spices. So once the external conditions are met, it is very likely to become a fragrant stone, but it is still unknown how long it will take to absorb the fragrance.
