SinusFree
This spicy, pungent liquid supports the free flow of mucus and facilitates breathing. Its ingredients reflect the botanical experience of cultures throughout the world. Included are yarrow, thyme, eyebright and horseradish. Their essential oils produce a gentle stimulating effect that supports healthy mucosa and promotes mucus circulation. Yarrow, thyme and eyebright are also rich in flavonoids, helping to stabilize mast cells and reduce histamine release.
SinusFree was formulated by Jill Stansbury, N.D., a naturopathic physician since 1988.

Freeze-Dried Stinging Nettles
Stinging nettles have been long renowned for tonification and more recently for sinus support. Planetary Herbals Freeze-Dried Stinging Nettles are organically cultivated. Freeze drying helps preserve the potency of the active constituents, which include histamine, serotonin and acetylcholine. The suggested daily use, two tablets, supplies the dosage used in clinical studies. In vitro research has shown freeze-dried nettles to inhibit arachidonic acid and leukotriene production.

Three Spices Sinus Complex
This formula is modeled after the famed spicy Ayurvedic herbal compound, Trikatu. Planetary Herbals was the first American company to introduce Trikatu to the American health food market. This blend contains the aromatic and pungent spices, long pepper, ginger, and black pepper. Less than optimal digestion may cause protein molecules to enter the bloodstream and evoke an immune response. When the respiratory passages are exposed to environmental proteins (pollens or molds), the immune system is further stressed. The spices in Trikatu have traditionally been used to avoid immune response by supporting protein digestion, the lungs and sinuses.
