Yeah, it works amazing for wasp stings I was once stung on the hand in winter by a hibernating queen moving some woodchip mulch bags, I went back to the car immediately put some comfrey oil on it and by the time I went to pay and walk back to the vehicle the sting was gone. With previous wasp stings, without anything put on it it could take around 2 weeks for things to calm down, so well worth it if you ask me.
