Can Huoxiang Zhengqi Water, which contains ethanol, be applied to treat prickly heat?
Agastache medicinal liquid contains ethanol and can usually be applied to treat prickly heat. It is recommended to use the medication under the guidance of a doctor.

Agastache medicinal liquid is a common traditional Chinese medicine preparation. Its main ingredients include pogostemon cablin oil, Angelica dahurica, tangerine peel, platycodon root, ginger, and others. Some of these components have effects of clearing heat and detoxifying, removing dampness, and relieving itching. If prickly heat is caused by damp heat and is a mild skin symptom, applying an appropriate amount of Agastache medicinal liquid on the affected area after ensuring the skin is clean and dry may provide some relief.
However, it should be noted that Agastache medicinal liquid contains ethanol, which may cause some skin irritation, especially for individuals with sensitive skin, such as children or on delicate skin areas. Before use, it is advisable to test on a small area of skin to check for allergic reactions or other adverse effects. Although Agastache medicinal liquid may have some therapeutic effect on prickly heat, it cannot completely replace professional medications.
Maintaining good personal hygiene habits and wearing breathable clothing in daily life can help prevent the occurrence of prickly heat.
