Yes you can. You may also want to look into probiotics to build up the good bacteria that was destroyed when you were taking antibiotics. Next time around, you can get grapefruit seed extract, it is a powerful natural antibiotic. I used this to keep my toddler from getting sick when my husband was in December and I caught a cold from him and mine only lasted 2 days while my husband was sick for nearly a month and he doesn't take anything natural like me. Also try using the juice from a fresh lemon everyday. I usually cut the lemon in two and squeeze the juice into a glass of spring water twice a day. Lemons are naturally antibacterial and antiviral. They help heal the throat, they may be acidic, but when in the body they neutralize. I give my toddler echinacea, she still has yet to get sick in her life and she is going on 3 soon. I use all natural appraoches with her and myself and we have never been healthier. It is amazing.
