WuLong Tea?

I ordered a shaker from eBay which arrived broken. To apologise the very nice chap has sent me a box of WuLong tea along with the replacement shaker. It seems to be a diet product judging by the packaging.

Any ideas if this is ok to have?

The ingredients are:
Oolong tea, hawthorn, lemon grass and orange peel.

Thanks

I think the lemongrass and orange would rule it out

Thanks Starlight. Glad I didn't actually buy them then!
