Frankincense
Frankincense has astringent, purifying and anti-heat/redness properties. It is most beneficial to the respiratory system and the skin. It enhances immunity, calms the nerves, and promotes a relaxed state of mind. Traditional uses have included chewing the gum for strengthening the teeth and gums and stimulating digestion, inserting the resin into painful teeth, applying to inflammations, inhaling the vapor for headaches, in eye washes to treat soreness and infection, and dissolved in milk for cough.
