Several business owners in Westlake and East Hollywood have been charged with practicing medicine without a license after two victims became sick and had to be hospitalized.

The Los Angeles city attorneys office began an undercover investigation of Excellent Nutrition, J&R Beauty Supply earlier this year soon after a woman and her son visited the business complaining of flu-like symptoms.

The woman was prescribed an injection made up of a mix of penicillin and eucalyptus extract by a man identified as Miguel Juarez. The mother immediately suffered an allergic reaction; she was trembling and had trouble breathing.

Rather than call an ambulance, a woman at the business identified as Rosaura Juarez rushed her to the hospital. A week later, the son was admitted after vomiting and suffering chronic stomach pain.

Nine people have been charged with illegally selling dangerous drugs and praticing medicine without a license. Each violation carries a maxium sentence of one year in jail and a fine of $5,000 to $10,000.

"The unlicensed practice of medicine and dispensing of medicines and illicit drugs poses a serious threat to our most vulnerable residents, City Attorney Carmen Trutanich said in a statement. Especially the elderly and young children.
