It DOES NOT hurt your liver
Bought it in November and I think I used it enough to the point I'm able to go through a review. First of all, it almost a certainty it doesn't hurt your liver. When dosing Gotu Kola it's the first thing you normally test, due to its fame having liver toxicity. I researched a lot about it and I would say it's liver toxicity is linked to heavy metals from questionable sources. ND tests heavy metals and is not only a trustable source, but the most trustable one. On top of that, I tested the gotu kola i bought here in three people and we took exams after 3 weeks of dosing, and nothing happened to our livers. Overall, pharmacology is not linear, so I can't say for sure, but I would bet a good money on Gotu Kola not hurting your liver.
About the cognitive effects, I will just say I test my brain in different tasks, for more than 3 years, and the first day after taking Gotu kola, I broke two records I thought I never would, (or at least never without something very strong in terms of stimulatory effect). It was not the case, my brain was just very clean and sharp, and seems like my synapses got a bit stronger, but it can be just placebo effect and to be honest It's almost impossible to isolate this effect on me since I take a handful of things. To counter this, I tested it on my brother for 3 weeks, and his brain overall capacity increased, but I don't know to which extend. One thing i'm sure tho: the homeostatic effect is very strong on this one, with the sharpness and mental clarity decreasing very fast (they still there tho, you just don't feel it anymore)
About the skin: funny enough, it was the strongest effect. I'm already very committed to skin care (coq10, sunscreen and other basic things) and Gotu Kola took my skin to another level. To finish this review, I will just point out that, if you are more interested in the cognitive effects, go for the tablets. I didn't buy it yet, because I wanted to test the powder first, but the powder having nowhere near the effects of the tablets and yet being very strong just means one thing.
Thanks ND for being such a great company
