each plant has its own unique alkaloid profile, this is a result of its genetic make up and the einvironmental factors benefitting it to grow.
each of the above mentioned species, is better understood as phenotypes, there are known patterns in our collections and many more in the wild
each plants genes can have a relationship between how it appears and its medicine content, or none at all. its up to the plant and the environment again. so its not a sure bet that two simmiliar plants would have the same effect or a different effect
heck ive seen a hundred + year old plant have arms with 5 ribs up to 10 ribs, on the same plant. so in regards to rib count to characterize medicine, id say that is the least reliable.
a wild 4 rib is extremely rare and ive only found it twice, but i usually find that mutants have more potency than their local peers
bridgesii monstrosse as an example, got me on this hunch.
personally you couldnt sneak a TBM brew by me, it has a certain smell and taste, even compared to non monstrosse bridgesii it is clearly a different brew. and the huaraz clones are very different than the bridgesii's monstrosse or not, same thing goes for the matucana wilds/ but theres so much diversity there it gets hairy to say what phenotype it is
pc is also clearly an identfiable flavor, just as cuscoensis is a slightly sweeter version of that in flavor and aroma.
i think its obvious what the tea is by color/ smell/ experience/ taste/ however mostly because im the brewer, if a stranger made it i wouldnt have my method as a constant and it would open up another dimension of variables
grow plants, make tea, love life
