Fresh garlic, peel it off and insert it into her vagina every night then in the morning, u bring it out and wash yourself, night again u peel another one and put inside sleep with it till the following morning it will kill the infection inside and the smelling will stop... In case u don't know, garlic is a very strong antibiotics... Its very natural as well. No harm.
