I know it sounds like a lot but that's what Buhner recommends please correct me if I'm wrong.

For new tick bites, Stephen typically recommends taking astragalus – 3,000 mg daily for 30 days, 1,000 mg daily thereafter, indefinitely. Also: using a paste made of andrographis tincture mixed with green clay, the paste applied on the tick bite area can often prevent an active infection.
