Heal skin infections with the antiseptic, analgesic, anti-inflammatory, antioxidant, antifungal and antibacterial properties of tea tree essential oil. Tea tree oil is highly valued for its tissue regenerative properties. Apply it directly to the skin to help heal boils, skin lesions, scrapes, cuts, rashes, scars, athlete's foot, nail fungus and ringworm. Blend equal parts of thyme, lavender and tea tree oils to help heal ringworm. Apply the mixture to ringworm patches three times a day, for 10 days. Mix 2 tbsp. of cranberry carrier oil with 30 drops of tea tree oil and apply twice a day until fungus is healed. Almond, grapeseed or pumpkin oils may be a substitute for cranberry.
