In the pharmaceutical field, it is an important ingredient in many topical ointments, nasal drops, and cough syrups, providing relief from pain and discomfort. In daily necessities, the natural menthol added to toothpaste and shower gel provides a refreshing sensation during brushing and a cool, invigorating feeling after showering, bringing a pleasant user experience, like adding a "happy seasoning" to daily life. Its advantages lie in its natural safety and significant efficacy. However, it's important to note that natural menthol can be irritating to the skin, and those with sensitive skin should use it cautiously, just as delicate flowers cannot withstand strong winds and heavy rain. Excessive use may also cause adverse reactions such as skin allergies.
