Studies have shown stinging nettles have demonstrated both promising mechanisms and clinical results for supporting nasal passageway health such as hayfever support. While further study is needed, trials have shown stinging nettles demonstrated measurable differences vs. placebo after only one week.
Among the flavonoids, quercetin is one of the most biologically active. One of the best studied effects of quercetin is its ability to prevent mast cells from de-granulating during an allergic response. In preventing mast cell de-granulation, quercetin prevents the release of histamine, one of the major triggers to the overall allergic response.
A strong pineapple enzyme, bromelain has proven mucolytic properties. As such, bromelain supports normal mucousal tissue function and enhances the absorption of quercetin. Bromelain is the term used to describe a group of enzymes derived from the stem and fruit of the pineapple plant (Ananas comosus). As a plant enzyme, Bromelain has many advantages and uses as a supplemental ingredient. Bromelain has an “Approved” status by the German Commission E for micro inflammations (allergic reactions, localized internal infections). Other activities associated with Bromelain include inhibition of platelet aggregation, decreasing the viscosity of mucus (mucolytic), antibiotic activity and smooth muscle.
N-Acetyl L-Cysteine (NAC)
An amino acid that is a natural mucolytic, NAC reduces the viscosity of mucus. Studies have shown individuals have been treated effectively without side effects when given NAC.
