I also probably wouldn't eat a raw bulb of garlic.
I actually quite regularly eat raw garlic. It's a habit that I've got into since I found that ticks won't bite me if I regularly eat it a few days before a mountain trip. I've been doing this for a few years now with 100% success rate even though I've found ticks on me. It's better to swallow a clove whole rather than chew though.
There was one incident in 2010 when my partner and I were holidaying in the far north of the highlands of Scotland. We stopped at a lay-by along the road because it was August and the was Gorse bush everywhere with lovely yellow flowers. We walked into it, me with the intention of getting some photos and my partner with the intention of looking at the rocks more closely. That's when we realised that we were covered in ticks.
So we scurried out and spent literally the next hour picking well over a hundred or so ticks off us, none of which was larger than a millimetre or so. And you had to get them in the right light before you could see the sun reflecting off their backs sometimes. I remember someone was watching us and his puzzlement turned into horror when he realised what we were doing. They soon drove off in a hurry.
After we had picked all the bloodsucking ticks off, we couldn't really be confident that there weren't more on us that we had missed. You just can't take a chance with Lyme disease. I knew that I had some garlic bulbs in the glove compartment in the car so I figured, I could probably eat most of a bulb raw and minimise the chance of a tick biting into me. My only concern was that it might take a day or two for the garlic to have an effect. I was wrong.
I got some water and started chucking back the cloves and swallowing them whole with water. At one point, the action made me burp and my partner describes it as a garlic version of a pepper spray hitting his nasal passages. Being in the confined space of a small car probably didn't help.
We decided that it was probably a good idea to book a Bed & Breakfast for the night rather than camp so we could inspect ourselves for ticks in privacy. So after driving to the north coast we found a B&B with a vacant room, went in, stripped off naked and checked each other for ticks. We couldn't find a single one. Yay! The surprise came the next morning though when I had my daily poo. The smell of fresh raw garlic mixed with underlying peaty undertones stank out the whole cottage and forced my partner outside, swearing loudly and looking rather disturbed.
