Is there any interactions between cephalexin and mother's milk tea?

Lack of data: Herbals often lack studies looking for drug-drug interactions. Mother's milk tea has a mix of herbs with a reported area of benefits (and problems). Fortunately, Cephalexin has few drug-drug interactions, making one here unlikely. The main risk of cephalosporins is diarrhea and yeast infections, so watch for that rather than drug-drug interactions with your herbal tea.
