1- My AC pills are from Nature’s answer and I got them online at iherb.com.
2- Don’t waste time and call 112! Don’t panic, induce (or NOT, depending on the school of thoughts) vomit and take an activated charcoal pill. Nevertheless, in some cases taking AC might be even worst an enhance the poisonous effects of the plants. I think I would ask the 112 lines first unless I would be 100% sure.
