This Camphor Tincture is perfect for alleviating muscular aches, arthritis, rheumatism and backache. Camphor applied to the chest and neck can help relieve congestion and ease coughing. Inhaling camphor fumes relieves airway congestion and loosens mucus. When camphor is rubbed into the chest and throat, your body heat helps to release the camphor vapors that act as a decongestant.
