Recommended by holistic veterinarians, Herbsmith Rx Morinda Hindend Support is a Traditional Chinese Veterinary Medicine (TCVM) herbal formula designed to address Wei syndrome in horses, a pattern of chronic progressive hindlimb weakness rooted in Kidney Yin and Qi depletion. This nine-herb formula tonifies Qi, nourishes Yin, strengthens the hindlimbs, and warms the back and Kidney Yang to support musculoskeletal function and vitality in horses experiencing age-related or stress-related hindlimb decline. Available in traditional powder (500g, 900g, 1200g) and Flax Plus (30-day and 60-day supply); a six-tablespoon scoop is included with the Flax Plus format.

What It Supports
- Hindlimb strength and function: Addresses chronic progressive hindlimb weakness (Wei syndrome) by tonifying Kidney and overall body Qi, nourishing Yin, and restoring the energetic foundation that sustains musculoskeletal strength in the hindquarters.
- Kidney Qi and Yin tonification: Targets the root deficiency pattern underlying Wei syndrome — Kidney Yin and Qi depletion — which develops gradually with age, overwork, or chronic stress and progressively weakens the skeletal system, particularly the lower back and hindlimbs.
- Back and lumbar support: Warms and tonifies the Kidney and lower back, supporting the structural integrity and energetic function of the lumbar region that governs hindlimb strength in TCVM.
- Qi and Blood circulation to the hindquarters: Moves Qi and Blood to the lower body to support normal circulation and musculoskeletal nourishment in the hindlimbs, complementing the formula's tonifying action with improved tissue perfusion.
TCVM Principles
- Primary action: Tonify Kidney Qi and Yin, strengthen the hindlimbs, warm the back and Kidney Yang, and move Qi and Blood to the lower extremities.
- Approach: In TCVM, Wei syndrome describes the chronic progressive development of hindlimb weakness resulting from Kidney Yin and Qi depletion. The Kidney governs the bones and lower back; when Kidney Qi and Yin are depleted through aging, overwork, or prolonged stress, the skeletal system weakens progressively, beginning in the lower back and hindlimbs. This formula tonifies Kidney Qi and Yin to address the root deficiency, warms Yang to support the Kidney's energizing function, and includes Qi-moving herbs to restore normal circulation to the affected region. Treatment is typically long-term given the chronic, progressive nature of Wei syndrome. Not for use in pregnant mares.

Active Ingredient TCVM Actions
Morinda Hindend Support combines nine herbs that together tonify Kidney Qi and Yin, warm Yang, nourish Blood, and direct the formula's action to the lower back and hindlimbs:
- Ba Ji Tian (Morinda officinalis) - Morinda root: The chief herb; tonifies Kidney Yang and Essence, strengthens the sinews and bones, and expels Wind-Cold-Damp from the lower body; directly addresses Kidney Yang deficiency underlying hindlimb weakness and lower back stiffness in Wei syndrome.
- Shu Di Huang (Rehmannia glutinosa preparata) - Cooked Rehmannia root: The primary Yin and Blood tonic; tonifies Kidney and Liver Yin, nourishes Essence and Blood, and provides the Yin-nourishing foundation that balances the formula's warming Yang herbs and addresses the Yin deficiency component of Wei syndrome.
- Dang Gui Tou (Angelica sinensis) - Chinese Angelica root head: Tonifies and invigorates Blood, supports Blood quality, and nourishes the sinews and tissues; ensures the hindlimb musculature is nourished by healthy Blood as Qi and Yang are restored.
- Fang Hua Fen - Apsis: Included as provided in the formula's ingredient list; consult your authorizing veterinarian for specific guidance on this ingredient's role in the formula.
- Huang Qi (Astragalus membranaceus) - Astragalus root: Strongly tonifies Wei Qi and overall body Qi, supports immune function, and lifts Yang Qi; provides broad Qi-tonifying support that strengthens the body's energetic foundation and supports tissue repair and vitality in the hindquarters.
- Wu Yao (Lindera aggregata) - Lindera root: Moves Qi, disperses Cold, and warms the Kidney and lower body; addresses Qi stagnation and Cold obstruction in the lower body that can accompany Kidney deficiency and contribute to hindlimb stiffness and weakness.
- Du Zhong (Eucommia ulmoides) - Eucommia bark: Tonifies Kidney and Liver, strengthens the sinews, tendons, and bones, and stabilizes the lower back; one of the most important herbs in the materia medica for directly strengthening the skeletal and connective tissue of the lower back and hindlimbs.
- Gui Zhi (Cinnamomum cassia) - Cinnamon twig: Warms the channels, disperses Cold, unblocks Yang, and opens the circulation to the limbs; warms and activates the flow of Qi and Blood through the extremities, supporting circulation to the hindlimbs where stagnation accompanies Kidney Yang deficiency.
- Chuan Niu Xi (Cyathula officinalis) - Cyathula root: Invigorates Blood, expels Blood stasis, tonifies the Liver and Kidney, and directs the formula's action downward to the lower back, hindlimbs, and hind hooves; the guide herb that focuses the combined tonifying and moving action specifically to the lower body where Wei syndrome is expressed.
Potential Drug Interactions
Herbsmith Rx Morinda Hindend Support contains Yang-warming, Qi-tonifying, and Blood-moving herbs including Gui Zhi (Cinnamon twig), Dang Gui Tou (Angelica root), and Chuan Niu Xi (Cyathula root), which may interact with certain medications. Horses on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in horses remains limited. Not for use in pregnant mares.
Medication categories warranting extra caution include anticoagulant or antiplatelet medications (Dang Gui and Chuan Niu Xi have Blood-moving properties that may have additive effects), corticosteroids or immunosuppressive drugs, medications for musculoskeletal conditions, and horses managing multiple concurrent prescriptions. Your veterinarian can determine appropriateness based on your horse's condition, current medications, and laboratory results.

Frequently Asked Questions
What is Wei syndrome, and is Morinda Hindend Support appropriate for my horse?
Wei syndrome in TCVM describes the chronic, progressive development of hindlimb weakness resulting from Kidney Yin and Qi depletion. It typically presents as gradual loss of hindlimb strength, coordination, and muscle mass, often worsening with age, overwork, or prolonged stress. Morinda Hindend Support is most commonly recommended for older horses or horses with long-standing hindlimb weakness patterns consistent with Kidney deficiency. A TCVM-trained veterinarian can confirm whether your horse's pattern is appropriate for this formula before authorization.
How is Morinda Hindend Support administered, and what are the recommended doses for a 1,000 lb horse?
For the traditional powder, administer two tablespoons twice daily for the first 20 days, then two tablespoons once daily. For the Flax Plus format, administer one scoop (six-tablespoon scoop included) twice daily for the first 20 days, then one scoop daily. Mix into grain for easy administration. If the horse is reluctant to eat herbs, begin with small amounts in grain and gradually increase, or choose the Flax Plus version. Confirm dosing for horses of other weights with your authorizing veterinarian.
How long does it take to see improvements in hindlimb strength, and can this formula be used long-term?
Because Wei syndrome is a chronic, progressive deficiency pattern, response to herbal support is gradual. Most horse owners begin to notice improvements in hindlimb strength, stability, and overall vitality within 4 to 8 weeks of consistent daily use, with continued improvement over longer treatment courses. Given the chronic nature of the condition, long-term use is often appropriate and may be necessary to maintain and build on improvements. Your authorizing veterinarian will guide the appropriate duration based on your horse's response and pattern.
Can Morinda Hindend Support be used alongside other Herbsmith formulas?
Yes. The Flax Plus format combines the herbal formula with ground flaxseed, adding Omega-3 support for joints, coat, and cardiovascular health alongside the hindlimb-strengthening benefits in a single daily feeding. When combining with other supplements or prescription medications, always consult your authorizing veterinarian to confirm compatibility with your horse's full health protocol. This formula is not for use in pregnant mares.
