Dear Martha,
I find your question appreciable, and it would
be a pleasure to explain you.
Before i answer your question,Let me evoke
myself about the usage of improperly translated
terminologies of ayurveda which may never convey the
complete and accurate sense of the original sanskrit
terminology.I feel embarrased, when i come across such
terminologies quite frequently being used by our
group members who have UNDERSTOOD ayurveda.I think
its high time ,that we realise the rich terminology of
ayurveda and get confined to it,to serve our ayurveda
much better.
My intension is to purely unfold my
profound feeling,my regards to the medical system and
drive it better.I have my respects for one and all and
im not against anyone in saying so.Lets carry the rich
heritage of ayurveda in a much more better way.
Coming to your case, im worried what you meant
when u said cooling? Did u mean sheetaveerya? Well,
guduchi [raw] is ushna veerya and guduchi satwa is
sheeta veerya.Guduchi satwa [sheeta veerya] is being
opted to pacify the ushna veerya of aswagandha and
trikatu as well.
Aswagandha is balya,brumhana and rasayana.Trikatu
is having gunas of deepana and pachana which
facilitate the JATARAGNI further favouring the
brumhana karma of aswagandha.
And about the steps 2 and 3..those three are
the ingredients to be mixed together to get a single
dose.i.e 3GRMS of ASWAGANDHA and 1.5grms of TRIKATU
and 1grm of GUDUCHI SATWA.

I would be privileged in letting you understand
further clarifications if any.
