Never expected supplements/herbs to help this much. But Ive been taking them for around 1 month and its really calming. Like il still get anxiety but its not those uncontrollable heart palpitations that I had. Fyi my heart rate used to be at 105-115, now its at 75 with anxiety (I suffer from cardiophobia, so this is really great for me). Its great. Thankfully I didnt choose the SSRI route because it causes permanent damage like r/PSSD
