Ian, if you notice they purport HBH to contain "essential oils such as lemon grass and spearmint". Thymol is also considered an "essential oil" and is not specifically stated, nor is it specifically eliminated as an ingredient to HBH. Its not a "scientific analysis" but when I sniffed HBH, my nose definitely detected a hint of thymol odor. If in fact my nose is accurate and depending on the concentration, there may be some scientific basis to their claims.
