need help- info about raw leaf juicing

A friend has prostate cancer that has spread. He wants to juice with the raw leaves and I have searched the web but have a few questions about this process. This is serious so please DO NOT answer if you don't REALLY know what you are talking about please. The info on the web is conflicting.
1.The age of the leaf? I've read 70-85 days. My plants are that old before flower. Can the leaf be from veg stage or does it need to have been in the flower room. If it needs to be in the flowering stage how long once in the flowering stage?
2. Do the leaves need to be green? By the time the leaf is about 2 weeks from harvest, many start to turn yellow and have brown spots etc. Does that matter? I'm not sure it is the chlorophyll that matters anyway but not sure.
3.I use organic nutes but I dropped a bomb for mites in veg and the flowering room. I know that you should use organic leaves. We can't find any stricly organic growers as insects are always an issue here. I have tried to wait 2 weeks after the last bamb before I harvest any leaves. I know it isn't ideal. Is there any way to get the residue off the leaf before juicing, ie "fit", soaking?
4.Any other info that someone has would be greatly appreciated. Of course this is a time sensitive issue.

Leaves stems sticks twigs etc have no more then 10% thc. This means if you have 100 grams of it you are LUCKY to get 5-10% return
this means if you have 100 grams it's actually 10 grams of "usable area" then the ratio is about 10% return so for ever 100 grams you are lucky to get 4-5-10 grams sure the math is lower as I have done it before and well it's a hassle but worth it if you are out.

Trics are going to age along with the plant so its based on how you are growing it. so if your plant is just poping up... no thc till you can see it about half way thru flowering or a bit before...



if using fan leaves DECARB them it will raise the thc and cbd slightly..


look up rick simpson oil

Thanks for the quick reply. I am aware of the low thc in fan leaves them but I would be throwing them away so it's a free resource for him. I read 15-20 fan leaves is 1 dose. I can supply him with that and he can freeze them. I have never heard of DECARBing a leaf. How do you do that. Remember these leaves cannot be dried or heated or smoked. For this process they need to be fresh. Also I have read a lot about Rick Simpson and watched all the videos. Thanks. I make honey oil with butane out of the sugar leaf but not the darker oil that Rick uses. There is no way I could sacrifice good bud for that. Do you know if I can use all of the leaf to make Rick Simpsons brew and what the difference is between the effect of the honey oil and the Simpson oil?

decarbing varies generally with buds it's about 25mins at 225 deg in a normal oven. simply cover them with tinfoil and cook at 25 mins for buds.. leaves I would say if fresh lay them in the sun 1 day and your pretty done with it. depends on the heat and freshness of leaves.

the leaves will be heated but not in the smokeable since. once you have cooked them add oil and cook as you would for oil.
