For an aromatherapy gift basket, considering lemon oil is also wise, as it serves as an anti-stress agent. Tea tree oil and thyme oil can also be a part of the gift too. Tea tree oil is used externally as an anti - fungal, antiviral, antimicrobial, anti - parasitic, and antiseptic. Include Geranium oil, as it is an astringent, antiseptic, and a diuretic.
