It is an Std.. there is no cure.
No.It is a combination of trimethoprim and sulfamethoxazole called cotrimoxazole. It is mainly used for anti microbial .
Yes
yes
No, goldenseal will not cure STD's. It is used as an anti-inflammatory, antiseptic, astringent, bitter tonic, laxative, and muscular stimulant.
depends have you had unprotected sex, it may be a STD
Infection with HIV is the STD that can lead to AIDS. There is no cure, but many effective treatments.
You do not have syrup of chloramphenicol, of ofloxacin, of cefixime, of amoxicillin, of cotrimoxazole. They all are in suspension form.
