Not sure, have not used this.
I was interested in this til I researched Swertia Chirata and found that not only it is a medicinal herb that had been over exploited and on the verge of extinction, but the supplies of it are commonly adulterated. So in any case, theres no way this herb can be ethically sourced or guaranteed pure. I wont be using even though it looks like a decent formula otherwise.
