EFFECTS: Warming spleen-yang and purging cold accumulation.
INDICATIONS: Cold accumulation marked by constipation, or chronic dysentery with whitish and reddish mucus,
abdominal pain, cold limbs, deep and wiry pulse.
ANALYSIS OF FORMULA: This is a representative formula for deficiency of the spleen yang with cold accumulation. If
only to purge the cold accumulation, it may injure the middle-yang; if only apply warming therapy, it will be difficult to remove
the cold accumulation. So the only method is to warm the spleen yang and to purge cold accumulation simultaneously. The
combination of Zhi Fu Zi (prepared aconite lateral root) and Da Huang (rhubarb), both as the main herbs, warm the interior for
dispelling cold and purge the cold accumulation. Being pungent flavor and hot nature and as the assistant herb, the Gan Jiang
(dry ginger) specializes in warming the spleen yang to assist Zhi Fu Zi (prepared aconite lateral root) in expelling cold
coagulation. Hong Shen (Ginseng) is the adjuvant herb, with sweet flavor and warm nature, to invigorate the middle qi as well
as preventing injury of the spleen and stomach qi caused by over purgation. As the dispatcher herb, Dang Gui, Gan Cao
(licorice root) can strengthen ginseng in invigorating qi as well as harmonizing all the components.
This formula and Da Huang Fu Zi Tang (Rhubarb and Aconite Decoction) share the identical main herbs which are used to
warm the interior for expelling cold evil and purge the cold accumulation. In Da Huang Fu Zi Xi Xin (Rhubarb and Aconite
Decoction), Xi Xin (asarum root) is cooperated to dispel cold for assuaging pain, so it is applied to constipation due to cold
accumulation without deficiency of the middle qi. In Tang (Wen Pi Spleen-Warming Decoction), Gan Jiang (dry ginger), Hong
Shen (ginseng) and Gan Cao (licorice root) are cooperated to warm yang and to invigorate qi for consolidating the middle jiao,
so it is applied to deficient syndrome complicated by excess, i. e., deficient cold of the spleen and stomach complicated with
cold accumulation.
