I've used Hibiscus in tea form to lower blood pressure. There's Gotu Kola (no caffeine involved) that is generally good for calming down, concentration and anti-brainfog, so I use that every now and then. Raw garlic is good for detoxing and so on.

There are some relaxant type herbs such as that valerian, names like skullcap, even dandelion and the chamomile. Chamomile has worked but for some reason I get groggy and tired for drinking maybe too much of it at once. It's pretty sedating/relaxing and considered safe.

I'm sure there's a lot of those herbs if you have the time to look up some herbal dictionaries online etc. Some herbs may interact with certain medications though, so it's good to make sure if you got some meds going...
