I’m enthousiastic for discovering a whole new flavour on the spectrum. It is ‘nag champa incense’. And yes, that review on yunnansourcing using the same peculiar description is also mine, but that doesn’t make it less true :)
As for splitting the bamboo, there are some YouTube videos on that topic (then again, there are probably YouTube video’s on how to become a brain surgeon as well). I remember having decent results with a butcher style / chinese style kitchen knife, a spare hand to bang on the knife, and a relatively clean dustpan to collect the contents from all over the floor. YMMV.
I used a very small amount for a small evening session. Turns out you don’t need very much anyway, one brew after the other.
Flavors: Camphor, Eucalyptus
