It's worth saying that there are some herbal supplements with a demonstrated track record. For example, St John's Wort has seen use as an antidepressant, but it can also severely interfere with other medications. Ashwangadha has less consistent evidence, but may be useful for reducing anxiety in people with severe problems of that type.

Note the caveats. They might be "natural", but they still naturally interact with the world around them, and nature contains many allergens and poisons. They might in fact work for someone, but we've yet to isolate which chemical components are responsible for those effects, let alone optimize their ratio or dosage. In that respect, CBD products are somewhat further along the path of science than either of these two herbs.

With all of that said, I do recommend sticking to solutions that have evolved beyond the supplements aisle. (And on a bit of a tangent, remember that homeopathy is bullshit.)
