No problem, Quassia for me, has the same effect as other powerful anti-fungals like, garlic, oregano oil and Bicarbonate of soda.
Except it doesn't smell terrible or burn my insides. :|
For me, it has never stop working.
If I ever feel like some symptoms are returning, I know without doubt that Quassia will work and kill whatever is causing the problem.
I do feel strongly that after trying so many other solutions to candida problems, this is by far the strongest one. Simply because the candida cannot adapt to it.
How I use it is to put 1 teaspoon, into a teapot of boiling water. This tea is extremely strong. It has pungent bitterness to it, unlike anything else.
I'm used to it now, but let's just say. If lemon and garlic and diesel had a child it would taste like this.
A bag of 250g is roughly £10. So, using a teaspoon at a time, will last forever.
So... in short, Its extremely powerful, mega cheap, and totally natural.
Its best when used with Kefir to replace any lost bacteria.
Also its bright yellow, so you know its special. I worship the stuff.
