I haven’t had a lot of luck with that brand, but I know it’s popular so maybe some do. Bigelow Stress Free is one that has skullcap and worked well for me. But it’s a bit hard to find :/ which is weird because I actually really like the flavor too (rose and mint.) Rather than stress relief I use it as a sleep aid though - it’s more of a “lets you sleep” than “makes you sleep” which I like.
