Nettle Leaf Respiratory

Stinging nettle completes a satisfying arc: the weed that stings becomes the tea that soothes. Allergy folk-use runs deep — spring nettle for spring sneezes — and one small famous trial keeps the hope alive.

Here is nettle without the romance or the dismissal.

The One Trial Everyone Cites

A small 1990 randomised study of freeze-dried nettle leaf for hay fever found about half of users rating it helpful versus placebo — modest, self-reported, never robustly replicated. That single study powers three decades of marketing. Laboratory work adds plausibility (histamine-pathway interactions in vitro), but the clinical file remains essentially that one yellowed page.

What Nettle Reliably Offers

Nutrition, mostly: cooked nettle is genuinely rich in minerals (calcium, magnesium, iron) and vitamins A and K — a spring green with spinach-class credentials. Cooking or drying removes the sting entirely. As a warm tea it joins the respiratory-comfort beverage family on the usual grounds: warmth, hydration, ritual.

Root vs Leaf — Don't Mix the Files

Nettle ROOT carries a separate research file (prostate symptoms) with better trial support; leaf is the allergy-and-nutrition part. Labels and shoppers regularly blur them. For airway-season interest, leaf preparations are the relevant — and weakly evidenced — form.

Practical and Honest

Harvesting: gloves, young spring tops, thorough cooking. Tea: dried leaf steeped ten minutes. Cautions: nettle interacts theoretically with blood thinners, blood-pressure and diuretic medications; pregnancy skips concentrated forms. Allergy sufferers should hold proven management as the frame and nettle as garnish-grade experiment.

Nettle's honest rank: excellent vegetable, pleasant tea, allergy evidence thin as spring ice — and no less likeable for the honesty.
