Dang Gui Cong Rong is a Jing Tang TCVM herbal formula recommended by holistic veterinarians to moisten the Large Intestine and resolve impaction in dogs, cats, and horses. Based on the Dang Gui Cong Rong San from Yuan Heng Liao Ma Ji (Yuan-heng's Therapeutic Treatise of Horses) written by Yu Ben-Yuan and Yu Ben-Heng in 1608, this formula works to moisten the Large Intestine, move Qi, and resolve impaction, addressing the Large Intestine Dryness and Qi stagnation patterns that underlie constipation and impaction in small animals and horses. Available in a 90g Concentrated Powder, 0.2g Concentrated Capsules (50 count), and 0.5g Concentrated Capsules (100 count). Use as needed for up to 3 months. Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance.

Dang Gui Cong Rong works through complementary layers of Intestine moistening, Blood nourishment, bowel moving, Qi movement, fluid promotion, and food dispersion to address Large Intestine Dryness and impaction:
Dang Gui Cong Rong contains a potent purgative herb (Fan Xie Ye, Senna), Intestine-moistening herbs (Dang Gui, Huo Ma Ren), and Qi-moving herbs (Hou Po, Xiang Fu, Chuan Mu Xiang) that may interact with certain medications. Stop administration immediately if the patient develops diarrhea, vomiting, or other unusual signs. Pets on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in dogs, cats, and horses remains limited.
Medication categories warranting extra caution include laxative or stool-softening medications, gastrointestinal motility medications, anticoagulant or antiplatelet medications, and multiple concurrent prescription medications. Use as needed for up to 3 months, or as directed by your veterinarian. Your veterinarian can determine appropriateness based on the patient's condition, medications, and laboratory results.

Dang Gui Cong Rong is used in TCVM to address Large Intestine Dryness and impaction - a pattern common in dogs, cats, and horses with constipation and dry, impacted stools associated with Blood deficiency, fluid deficiency, and Qi stagnation in the Large Intestine channel. It is particularly well-suited to impaction patterns in horses, reflecting its classical origin in Yuan Heng Liao Ma Ji (1608), one of the most important classical Chinese veterinary texts. The manufacturer lists no contraindications, but stop administration immediately if the patient develops diarrhea, vomiting, or other unusual signs.
For horses, give 3g twice daily as a top dressing on feed, or as directed by your veterinarian. For dogs and cats using the 90g Concentrated Powder, give 0.1g to 0.25g per 10 to 20 lb body weight twice daily, or as directed by your veterinarian. For the 0.5g Concentrated Capsule format, give one capsule per 20 to 40 lb body weight twice daily; for small dogs and cats under 10 lbs using the 0.2g Concentrated Capsule format, give one capsule once daily, or as directed by your veterinarian. Use as needed for up to 3 months, or as directed by your veterinarian.
Fan Xie Ye (Senna) is included as the formula's primary downward-draining and bowel-unblocking herb, providing the active purgative action needed to resolve Large Intestine impaction alongside the moistening herbs. Senna is a potent bowel-moving herb, and diarrhea is a known risk with any Senna-containing formula. The manufacturer's stop-use warning specifically addresses this: stop administration immediately if the patient develops diarrhea, vomiting, or other unusual signs. This formula is intended for as-needed use for up to 3 months under veterinary supervision, not for long-term daily use. Your veterinarian will guide the appropriate dose and duration to minimize the risk of over-purging.
Huo Ma Ren (Cannabis sativa, Hemp seed) is one of the most important classical Intestine-moistening herbs in TCVM for constipation and impaction patterns rooted in fluid and Blood deficiency. It works by nourishing Yin and fluids and gently lubricating the Large Intestine to address the Dryness root of the pattern, complementing Dang Gui's Blood-nourishing and Intestine-moistening actions. Together, Dang Gui and Huo Ma Ren form the formula's primary moistening pair, addressing the Blood deficiency and fluid deficiency components that underlie Large Intestine Dryness, while Fan Xie Ye (Senna) provides the active downward-draining force to resolve the impaction itself.
