Thermal stability if Rhodiola and Ginseng Extracts

Does anyone know the thermal stability of both the rhodiola and Ginseng extracts. I recently ordered both and unexpectedly had to go out of town this past weekend. The package was delivered Saturday and as a result sat in my mailbox for almost two days. I live in the south where the temperature was about 95 F each day. I am a bit worried about the heat degrading either of the products. Any information on this topic is welcome.

You are not going to reach anywhere near the thermal decomposition temps of those products in a mailbox for a few days. At 35*C, it would take 20 days to reduce salidroside by 10% in a solution with a pH of 6. Salidroside just degrades into tyrosol anyway, which is active itself. Also, your products are not in a solution with a pH of 6. Tyrosol's boiling point would be 139*C, or 282*F. So you are not getting there in a mailbox. Ginseng is dried at 38*C during production. So it is already exposed to higher temps than your mailbox anyway. No worries there.
The only products I would worry about leaving in a mailbox for a few days would be pramiracetam, fasoracetam, and maybe alpha-GPC 99%.
