Dear Madam,
Bay leaf oil is used only for external use. To treat migraine, mix 1 drop of bay leaf oil with 5 drops of any other edible oil and gently massage the place which hurts (never use non-diluted oil!). For hair – you can pour 20 drops of oil in shampoo bottle or rub diluted bay leaf oil into the scalp (hair roots) (100ml of olive or almond oil and 30-50 drops of bay leaf oil). You can rub this mixture into your gums once a day (irritation may occur after a prolonged use – make a break after 2 weeks of use if you treat periodontal disease). This mixture may be used in massage if you have muscle cramps, sciatica, pain in muscles and pains in joints as well as varicose veins and broken capillaries. Always start with a small number of drops, then gradually increase this number (to avoid irritation).
Best regards
