Since I was a little kid I have known that tobacco juice is a better home remedy than costly Neosporin or anything else and ALWAYS keep a pouch of Mailpouch tobacco for things like poison ivy, mosquito stings, bee stings, athlete’s foot, or even, G-d forbid, ringworm or impetigo.
Soak some in water and put the wet tobacco right on whatever ails you and it works like magic. Old Indian folk remedy.
My grandfather made a foot soak with fresh tobacco leaves and hot water. Greenhouse managers use tobacco ‘candles’ to kill insect pests. ... And I smoked for decades and gave them up about eight years ago ... but I would pick them right back up if they figure out how to stop the components of tobacco from causing disease.
