I have tried it plantain TeeDee, and while I was hopeful, and it took the edge off the misery, overnight the whole arm swelled up anyway and my elbow was pretty much immobile.
This is a histamine reaction, and if you're susceptable then it can be a massive reaction. It literally immobilises a limb if I'm bitten there. On my hand or foot and it's beyond miserable. One on my neck left me slightly panicky and my heart fluttering like a trapped bird in my chest. Thankfully the swelling went outwards and not into my throat.
It's not worth getting it wrong; the pills are easily available and they're not expensive. I don't normally take much in the way of medication, but the antihistamines and anti-inflammatories are a blessing.
I have tried the mugwort, the boor tree and the gale, and they all work, a bit. They discourage the blighters, but they don't stop them
Marmite and me are long term friends, and I still get bitten. I have tried the B vitamin patches (got a chemical burn from those
) and was quietly hopeful that they'd work. Not trying that again. I tried the Niacin (B3) tablets and that was a nightmare. Look up Niacin Flush and imagine that fireants are burrowing under your skin. Never mind a flush, it damned well hurts like the worst sunburn.
I've been very fortunate this year, long may it continue, and haven't been bitten by anything but the midges so far.
Clegs, horseflies…they're why the Devil's known as the Lord of Flies.
