 But Judy, when she gets stung by a mosquito, it really bothers her. The comfrey doesn't seem to work that well, for her anyway, on mosquito bites. Other people have told me that it works real well for them. Any kind of bite takes the itch and sting away quite fast. But some people have just a little bit different constitutions, and it doesn't work 100% of the time. But comfrey, C-O-M-F-R-E-Y, comfrey.
