denaturing powdery mildew?

my first harvest looks good except for a light dusting of what seems to me (from pictures I have seen in books) to be powdery mildew -- especially on and close to the stem / core of the flower. while i am taking more preventative appoaches for any future harvest, i am a medical patient and would like to save my weed because it's my medicine. my condition isn't lung related but still, I want to be as careful as possible. the flowers smell good; it's just the visible whiteness, the knowing that it is there that keeps me from using it with peace of mind. what can i do?

i am looking for a real, fact based method for denaturing the mildew in a way that will not denature the active ingredients of my medicine.

also, it's important to me that i maintain the organic integrity of my medicine.
thank you for taking the time to help me.

What i use is Serenade. It's natural and removes most mildew, rust, mold, etc.

Follow the instructions, then a day or 2 before harvest spray plants with clean water!

 

Sounds like mold and mold is VERY dangurus to smoke.
the last thing you want is mold in your lungs.
Mold = bacteria and bacteria = desies.
