Living Libations Salt Inhaler powerfully purifies with salt and essential oils. The salt particles combined with essential oil molecules bathe and fortify the breath. This simple tool is a breeze to use: undo the plug at the bottom of the inhaler, insert 3 to10 drops of essential oil into the base, and re-seal the plug. Hold the pipe to the mouth, inhale deeply, and exhale through the nose. Or try the yogic alternate nostril breathing method (Nadi Shodhana Pranayama). Repeat for up to 20 minutes. The Himalayan Salt is effective for 2 years, and essential oil drops are potent for up to 3 weeks.
