Hello there..
Nice that you have fresh Chacruna!
If you have Mapacho as well it goes as a nice combination but otherwise it's fine..
Boil these ones for a total of 10-12 hours.. change water 3 times and in the end reduce to 25-30cl.
Start by drinking 5cl then after 30-40min another 5cl.. feel it out and you will know if to stop there or continue drinking..
Good luck
