Siang Pure Oil helps me breathe deeply through my nose.
It's a combination of herbs that I apply under my nostrils to help me breathe through my nose more easily. Like a more powerful version of eucalyptus.

Based upon a formula passed down through generations of traditional Chinese medicine practitioners from the Shantou region, Siang Pure Oil is made purely of herbs without any chemical additives. Ingredients include menthol, peppermint oil, clove, camphor, and cinnamon, which give the oil its well-known brown-yellowish color. Siang Pure Oil has properties similar to smelling salts and is predominately used to relieve dizziness and symptoms of fainting, but it can also be used to relieve indigestion, cramps, bone and joint aches, bruises, muscle pain and insect bites.
