Instructions on how to prepare lemon balm differ among herbalists. As with every herbal medicine, a qualified professional should be consulted before treatment.
In aromatherapy (to calm nerves and improve mood) the oil can be used much like the way lavender oil is used.
One can use the pure essential oil by dabbing some on a fabric sachet to a place near the bedside.
There are also skin lotions available.
As a topical treatment for insect bites and skin irritation from minor infection: a compress may be used.
A compress is made by steeping the leaves in hot water for a few minutes, and wrapping the leaves, once cooled, in a clean cloth or gauze.
As a tea, using one to five grams (one to two teaspoons) of dried leaves, it may be consumed several times a day. Lemon balm is also available commercially in capsule form.
Capsules are typically 300-400 mg each. Some herbalists state that it is safe to take as many as 9 capsules a day; however, a medical doctor should be consulted before taking lemon balm in prepared forms.
