Patchouli is not the first clinical recommendation to remove prickly heat, and the method is relatively uncommon. If it is needed in special cases, patchouli can be applied locally to the prickly parts and then kept dry and cool, or a small amount can be dropped into the bath or wiped on the body during bathing, which can be used to sterilize, disperse and relieve the symptoms, and reduce inflammation and itching. It can also be taken orally, but it should be noted that Huo Xiang Zheng Qi Shui contains 40%-50% alcohol, so it is not recommended for children, pregnant women, the elderly and infirm, as well as people who need to drive and patients who are allergic to the drug, and it should not be used in combination with cephalosporins, metronidazole, tinidazole and other drugs during the medication period. In addition to patchouli, TCM clinics usually recommend taking appropriate amounts of fresh amaranth, honeysuckle, wild chrysanthemum, or fresh aster, and decocting warm water to remove heat rash. In addition, patients may also choose to apply topical stove glycerine lotion and prickly heat powder topically, and for purulent prickly heat, topical ichthyolite stove glycerine lotion and yellow lily puff powder. Patients with pronounced itching can also take oral antihistamines under the guidance of a doctor to relieve the symptoms, which generally heal in 1-2 weeks. Patients are advised to keep the room ventilated and cool, use fans and air conditioners when necessary, change clothes regularly, and wear loose, light, breathable and sweat-absorbing cotton clothes to reduce friction on the skin.
