Yes sure these herbal mixed can cure this STD slowly. Not in one day or two.
Hvergerthi. This lady situation is getting worse. I personally do not agree herbs now is a good idea.
She better go to see the doctor to get injection especially penicilin to cure it first. Else I think her life would be in danger.
As I mentioned earlier it is impossible to say if it is likely to work since she refuses to say what the infection is. That is why I recommended going the doctor's route first so the herbs don't get blamed if they don't work.
