Does anyone know about CBDA and CBD?

I am trying to figure out what temperature CBDA becomes CBD. I know THCA becomes THC at 106C but i am interested in CBD for healing purposes. Also do CBDA and THCA have any medicinal properties, or any importance compared to CBD and THC. Basically can they be used by us or is the answer CBD and THC? I want to one day use CBD as a medicine without getting super high so i can ingest a lot more than normal.

Ahhh...Let's try to figure it out, then!

CBDA is the acid form of CBD (like THCA : THC).
aaaaaaaaaaand Google is my friend

http://theleafonline.com/c/science/2014/07/cannabinoid-profile-crash-course-cbda/

Formula: C22H30O4
Molecular Mass: 358.2144 g/mol
Decarboxylation Point: 120+ °C (248 °F)

Boiling Point: ????

LD50 (Lethal Dose): 5,000mg/kg for rats, Inhalation TCLO (human): 15,000 mg/m3 mg/kg (Compare to Nicotine: for mice – 3mg/kg, for humans – 40–60 mg/kg),

EDIT:In the vid, he says the CBDa decarboxylates at 80 degC.

thank you, google was not being my friend on this one, still having questions though

this guy http://www.marijuanagrowershq.com/decarboxylating-cannabis-turning-thca-into-thc/ tested THCA decarboxylation point but his labs results showed no decarboxylation with CBDA at around 240ºF but 80ºC is 176ºF,

the leaf online site also goes on to say on another page that the decarboxylation of CBD is 115-145°C (239°F to 293°F)...hasn't CBD already gone through decarboxylation?

Interesting.
I think that chart from Snaps is more useful. It tells a more complete story, in that different temps have different times before diminishing returns kick in.
It seems to imply hot (but not boiling/vapourizing) and fast is key. Which makes sense because as the process goes on, there will be some loss just because it is ultimately governed by energy transfer and enough energy will find its way into some molecules, oxidizing them or breaking them further.
So if it is done as quickly as possible, secondary losses will be minimized.

I was just reading another paper, Decarboxylation of D9-tetrahydrocannabinol: Kinetics and molecular modeling from 2011. In it, the study found on a range of 90-140ºC, 110ºC for 110 minutes yielded the highest return. But they noted (I think) that it was important to decarb the material before extraction.
They also used methanol; however, I don't think that is relevant to the discussion at hand. What is valuable are the results:

EDIT: I was just thinking about that last part 3.7E8 s^-1
370MHz... resonant frequency?
