Beyond carefully removing the tick (do not squeeze the tick body when removing it which can increase risk of infection) and applying some antiseptic to the bite, I do not do anything after a tick bite. Herbs are unlikely to reduce the incidence of Lyme, Rocky Mt Spotted fever, Bartonella, Babesiosis or other tick borne disease. So depending on what type of tick is on the person I have them watch for any possible symptoms. If none occur after 4- 6 weeks, they are most likely OK. For deer ticks some doctors prescribe prophylactic doxycycline (3 days), but the research suggests that it is not all that effective in preventing Lyme disease.
