Can "essential balm" be eaten?

Hello, landlord! "Fengyoujing" is edible, and it can treat colds, relieve abdominal pain, carsickness and so on. Pour it into warm water and mix it with water for drinking. Not directly, directly tastes bad. In addition, if you have a cold, you can pour the essential oil into the bucket, then pour half a bucket of boiling water and smoke for a few minutes. Take a bath after neutralizing the water again. This can prevent and treat mild colds! I hope it will help your problem!
