To the Editor: In their Research Letter, Ms Stjernberg and Dr Berglund1 documented a repellent effect of garlic against an unnamed species of tick and stated that daily consumption of 1200 mg of garlic was an alternative to "other agents that might have more adverse effects." Based on the design of their study, any conclusions concerning the relative effectiveness and safety of garlic as a tick repellent are unfounded. They compared garlic to a placebo, not to other currently available repellents, and they did not present any data on the comparative safety of garlic vs other repellents.
