Stinging nettle is one of the most important tonics of western herbal traditions and was traditionally used to support healthy sinuses. Modern research documents this use in biological assays demonstrating it reduces the biosynthesis of arachidonic acid and leukotrienes that play key roles in healthy immune responses and sinus health.
Planetary Herbals premium nettles have been freeze-dried to preserve the potency of the active constituents in the plant's stinging hairs and leaves. This process ensures that Freeze-Dried Stinging Nettles will deliver all the benefits inherent in the nettle plant. The suggested daily use supplies the same dosage used in clinical research on freeze-dried nettles.
