Is kava the same as CBD?

Could you please elaborate on the differences between kava and CBD? I've heard both mentioned in relation to natural remedies and relaxation, but I'm unclear if they're the same substance or have distinct properties. CBD, or cannabidiol, is derived from the cannabis plant, whereas kava is traditionally obtained from the root of the Piper methysticum plant. Does kava produce similar effects to CBD, such as reducing anxiety or promoting sleep? Additionally, are there any known interactions or contraindications that one should be aware of when considering either kava or CBD for therapeutic purposes? Clarifying these distinctions would be greatly appreciated.
