I have a number of questions. Much appreciated if anyone can help.
Is anyone here aware of any studies that compare STW effectiveness brand to brand?
When clinical research on SJW is undertaken they use formuals to exact specifications which may or may not contain "recommended" levels of hyp-whatever-it-is. Does anyone know which brands match specifications, or where researchers obtain their SJW and if what they use in the studies bears any resemblance to SJW obtained over the counter?
With all the talk about "standardized" SJW, does anyone know what that really means? Are standardized products required by law to contain certain ingredients? Who standardizes over-the-counter products in the first place?
Is anything known about quality control practices re individual brands?
Finally, any suggestions for Canadian brands?
Cheers
Andie
