Bracken fern JHS

Hello JADAM team,

Bracken fern is recommended as a replacement for Ginkgo berries in regions where Ginkgo is not available.
The JADAM Organic Farming book contains photos of fresh green bracken leaves being boiled.

But in our experiments, JHS made from fresh leaves (fresh bracken, oleander, jerusalem artichoke leaves or ginkgo leaves) always fails JWA test even if tested immediately after boiling. What I mean here is, when I pour such JHS in a measuring glass and put a drop of JWA in it, the drop leaves a milky colored trace, which, according to official JADAM videos, indicates that such JHS will reduce the power of JWA when mixed and thus such pesticide might be either less effective against difficult pests or not effective at all.

I have also read many times that fresh green ginkgo leaves are not recommended (in Korean language you call them 파란잎, "blue" leaves) and instead it is advised to wait until autumn and collect fallen yellow ginkgo leaves. It is said that yellow ginkgo leaves do not fail JWA test and do not reduce effectiveness of JWA.

So I have some questions.
1. Can I make JHS from leaves of herbs like bracken in such a way that it will not fail JWA test and will not reduce the power of JWA?
2. Would it help if leaves are dried first? 
3. Would it help if leaves are harvested in late autumn when they are yellow?
4. In your experience, is JHS made from yellow or dried bracken leaves better than JHS made from fresh green bracken leaves?

Thank you!

    When testing Jadam oil on water boiled in bracken, if the color of the water temporarily changes and the color appears normal again, it can be used as JHS.
    I have no experience with numbers 2, 3, and 4.
    Ginkgo trees are definitely best made in the fall.
