Can you buy kava kava over the counter?

I'm curious, could you please elaborate on whether it's possible to purchase KAVA kava without a prescription or through over-the-counter channels? I've heard about its potential benefits but am unsure about the availability and accessibility of this product. Are there any specific stores or retailers where I can find it? And if so, are there any regulations or restrictions I should be aware of before making a purchase? I'd appreciate your insights on this matter.
