Extract seems really good
Extract seems really good but labeling is probably out of date as customer service says their current kushen extract is standardized for Oxymatrine not Lupeol. Opposite of what label says. Apparently that's leftover from a previous version of the product. Not important to me... Might be problematic for someone else *Edit* given reply below I'd like to simply again point out to you that the label says 40% lupeol. Which both you and customer service agree it doesn't have (you just said 20% Lupeol). I don't care about Lupeol. I mean it's inclusion is fine. But I want oxymatrine (or alternatively matrine.) Apparently you removed matrine altogether. I probably don't prefer that, but whatever. I'd just again point out the label doesn't match anything either of your reps have said. Might want to work on that part.

We have always standardized for lupeol. The product is the same, but we adjusted the labeling recently to provide better information on what this product is. Our customer service rep might have, in an attempt to be more helpful, given their own interpretation of the labeling. Here's the thing: we remove the matrine to increase the lupeol, but have not found a way to remove the oxymatrine. So while we create a powder that is rich in lupeol (20%) we are still measuring quite a bit of oxymatrine (40%), so we wanted that info to be known on the label. Wish there was an effective way to remove more oxymatrine, however, our product has more lupeol than any other dietary supplement on the market. To address your edit: After further research, you are correct; it appears there was a typo in the labeling that indicated 40% oxymatrine. We are sorry for the error.
