Quercetin: Nature's Antihistamine and Senolytic
A Flavonoid That Fights Ageing and Allergies
Quercetin is a plant flavonoid hiding in everyday foods — onions, apples, berries, and broccoli. It's earned attention for two distinct reasons: it's one of the most effective natural antihistamines, and it's half of the most studied senolytic combination in ageing research. This dual identity makes it one of the most versatile supplements in the longevity toolkit.
