hey there and sorry that i open a topic before properly introducing myself- i will try to find the time for an introductory post soon!

now onto my question:
i extracted harmala fb from syrian rue about two months ago. unfortunately i had to store it at room temp (in a ziplock bag).
the thing is that the formerly almost white powder changed its color to almost orange.
i searched the nexus for quiet a bit to find out more about it but couldn't find anything on the topic.
My questions are:
1) did the color change because of oxidation or any other reaction (which one?)?
2)does anyone know if the extract is still okay to use without any risk for health?

that's it. i hope someone will be able to answer :-)
thanks in advance
