The disease is self-limiting and generally does not require antiviral treatment, but symptomatic treatment can be given, and drugs such as montelukast and nimesulide can be applied. It should also be noted that patchouli contains alcohol and should not be used by people who have to drive and those who are allergic to alcohol.
