Their detailed report, shared within the medical journal Advances in Respiratory Medication, brings collectively findings from lab checks, scientific trials that are rigorously managed research with volunteer sufferers, and real-life affected person use to color a transparent image of how this natural drugs performs.
Folks utilizing Ze 339 in research noticed the identical form of symptom aid as these utilizing widespread allergy medicine. Sneezing, runny nostril, and blocked nasal passages all improved after use. What stood out was that Ze 339 didn’t trigger drowsiness, a standard situation with many allergy medicines.

As an alternative of blocking histamine within the physique, a chemical launched throughout allergic reactions, it helps calm the discharge of gear that trigger swelling and discomfort. These embrace leukotrienes and cytokines, that are small proteins that sign irritation within the physique. Ze 339 reduces early signs by serving to stop the discharge of sure chemical compounds from immune cells, fairly than performing like conventional antihistamines. This twin method helps each the short and delayed allergy signs.
Dr. Schapowal additionally identified how helpful this natural extract could be for normal use. “Ze 339 not solely offers aid with out making individuals sleepy, however it additionally continues to work nicely over time,” he mentioned. Info from on a regular basis customers—individuals taking the product exterior of scientific trials—backs this up. Sufferers of all ages, together with these with bronchial asthma or pores and skin issues, reported feeling higher with few negative effects. A lot of the negative effects have been gentle, akin to slight abdomen discomfort, and didn’t cease individuals from utilizing the product.
Clear patterns from the analysis present that Ze 339 is a protected and dependable alternative for these coping with each varieties of allergic rhinitis—seasonal, which happens throughout pollen seasons, and year-round, usually triggered by indoor allergens. The report underlines that pure cures like Ze 339 deserve a spot alongside commonplace allergy therapies, particularly after they supply fewer negative effects. As a result of it doesn’t work together badly with different medicines, it’s an excellent possibility for many individuals. Researchers additionally instructed it would assist with different allergy-related circumstances akin to bronchial asthma, a situation that narrows the airways, or eczema, a pores and skin situation that causes irritation, though extra research will likely be wanted.
Current hints present Ze 339 may also assist battle viruses, giving it potential use past allergic reactions. Because it’s already accepted to be used in a number of international locations, including new makes use of could possibly be faster and simpler than ranging from scratch with a brand new drugs. With its confirmed outcomes, gentle negative effects, and distinctive means of working, Ze 339 might turn into a preferred pure possibility for allergy victims all over the place.

Legend of the Featured Picture
(1.) Remedy of main human leukocytes with Ze 339 led to decreased anti-IgE or complement C5a-stimulated LTC4 synthesis. (2.) GM-CSF-priming and complement C5a or PAF stimulation of eosinophils and neutrophils led to the synthesis of cysteinyl LTs and LTB4 which was inhibited by Ze 339. Moreover, therapy of stimulated eosinophils with petasin diminished the discharge of ECP. (3.) The therapy with Ze 339 resulted in decreased neutrophil migration in direction of HNEC supernatant. (4.) Ze 339 inhibited cytokine-induced JAK/STAT signalling. (5.) Remedy of stimulated eosinophils with petasin resulted in diminished intracellular Ca2+, diminished cPLA2 exercise and diminished 5-LO exercise. (6.) Ze 339 utility diminished histamine, cysteinyl LTs and LTB4 focus in nasal fluids of sufferers.
