I reacted to turmeric with large bruises along the insides of my forearms. They lasted for weeks. So the blood thinning part is no joke. (I am not on blood thinners, nor had taken a large amount of it.)

Garlic's medicinal properties are best utilized by using a garlic press and allowing the results to rest for a minimum of 10 minutes. I did a post on this.
