Melissa, or Lemon Balm, is a small herb native to central and southern Europe. It has a sweet, lemony smell liked by children and adults. Melissa is a very uplifting and calming oil and is useful for treating tension, stress headaches, migraine and nervous asthma. Melissa's anti-inflammatory properties are helpful for inflamed skin and allergic skin conditions. If diluted it can be used for ulceration, eczema and other skin complaints - particularly those which are stress related. It is also a good first-aid remedy for bee and wasp stings.
