It is considered an excellent physical tonic and boosts the immune system, which helps recovery from an illness. It also has great anti-bacterial properties, and has the added bonus of acting as a natural insect repellant. Combined with Calendula, its anti-inflammatory and antiseptic properties work beautifully for the skin while keeping the pesky critters away.
