Even if they worked (which they don't), I still don't think producing magic potions out of the killing of endangered species would be justified.

Unicorns,
Have unique horns,
But if you cut them off,
And grind them up,
Into a cup,
It will cure a cough.
The unicorn,
Who's lost its horn,
Will surely die, of course.
But to be fair,
Without it they're,
More or less a horse.
There's no justifying mangling a pangolin,
Even if you thought it cured the 'flu,
If it did, you're still a jerk,
But it doesn't actually work,
So it turns out you're an ignoramus too.
