We have a May Bloom here. I guess the R is a good rule of thumb to limit probability. So how shall we treat ourselves if we get had? (He leads)
I reckon wild plants wise, straight away go for the Plantains, Yarrow, Mallow followed by plenty of tea made from Bramble leafs, Pine needles, Gorse flowers, Wild water mint and Meadow sweet. In my own experience, as soon as you feel the first stomach cramps, run as fast as you can to the nearest hedge (especially when in unfamiliar company) and that was off a Limpet!
