The latter is chiefly made up of drugs for inducing resuscitation and those for warming the interior and used for apoplexy, invasion by cold, qi stagnation or mental confusion due to phlegm.
 
Excess syndrome of stroke is characterized by coma, but it does not necessarily follow that all coma is caused by obstruction of the heart orifice.

Besides aromatic drugs in these prescriptions should not be decocted to prevent volatilization or reduced efficacy.
