Will prolonged exposure to the smell of Chinese herbal medicine have any effect on the body?

Generally, exposure to the smell of traditional Chinese medicine (TCM) does not affect health, but individuals with allergic constitutions should avoid prolonged contact with TCM as much as possible. The detailed analysis is as follows:

In the process of TCM diagnosis and treatment, moderate exposure to the odor of herbal medicines can aid in disease identification and therapy—for instance, through olfactory examination to help determine illness. Moreover, certain TCM sachets or incense, when used appropriately, do not negatively impact the body and may even offer some health benefits, such as calming the mind or repelling insects. People who have long-term exposure to TCM may have already adapted to its scent, so they might not experience adverse reactions even when working in environments containing herbal odors.

However, certain individuals, particularly those with allergies, may experience discomfort or allergic reactions after prolonged exposure to the smell of TCM. If any symptoms occur, it is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified healthcare provider.
