I've temporarily disallowed anonymous comments, so you'll need a blogger account to comment for the time being. Some spammers are putting their questionable pharma sites in their "other" name, possibly hoping I won't notice and the insincere "Great article!" comment won't catch my attention. I've also turned on word verification.
Note for the handful of people who occasionally buy this stuff and make them enough money to justify the small amount of time they use putting up free advertising and wasting a disproportionate amount of my time: The stuff often isn't quality, and sometimes even unrelated to what they label it as. In the case of herbal stuff, it's a crapshoot: It's not uncommon for herbs to lack the active ingredient they were supposed to be grown for. They're environmentally unfriendly most of the time, as many are overharvested from the wild, rather than farmed. They're also commonly immune to most regulations, and can contain heavy metals.
Sorry for the inconvenience.
