Can you travel with kava?

Could you elaborate on the logistics and regulations surrounding traveling with kava? Is it permissible to carry kava across international borders? Are there any restrictions or quotas I should be aware of? Are there any special packaging requirements for kava to ensure its safety during transit? And finally, would it be advisable to declare kava to customs authorities upon arrival or departure, to avoid any potential legal issues? I'm keen to understand the entire process of traveling with kava and any related considerations I may need to take into account.
