Available in concentrated powder, concentrated capsules, standard powder, standard capsules, and teapills. Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance.

Active Ingredient TCVM Actions
Rehmannia 14 expands the classical Rehmannia 8 (Jin Gui Shen Qi Wan) base with six additional herbs to simultaneously address Yin, Qi, and Yang deficiency, making it the most comprehensive of the Rehmannia formula family:
- Sheng Di Huang (Rehmannia glutinosa, raw) - Raw rehmannia root: A foundational Yin tonic from the Rehmannia 8 base; clears Heat, cools Blood, nourishes Yin, and generates fluids to address deficiency Heat from Yin depletion
- Fu Zi (Aconitum carmichaelii, prepared) - Prepared aconite root: From the Rehmannia 8 base; strongly warms Kidney and Heart Yang and addresses deep cold-type Yang deficiency patterns as the principal Yang-warming herb
- Gui Zhi (Cinnamomum cassia) - Cinnamon twig: From the Rehmannia 8 base; warms the channels and unblocks Yang, promotes circulation of Qi and Blood, and assists Fu Zi in warming the Heart and Bladder
- Shan Zhu Yu (Cornus officinalis) - Asiatic cornelian cherry fruit: From the Rehmannia 8 base; tonifies Liver and Kidney Yin and Yang, stabilizes and binds to prevent leakage of Essence, and supports reproductive and urinary function
- Shan Yao (Dioscorea opposita) - Chinese yam rhizome: From the Rehmannia 8 base; tonifies Spleen, Lung, and Kidney Qi, stabilizes Jing, and supports digestive and metabolic function
- Mu Dan Pi (Paeonia suffruticosa) - Tree peony root bark: From the Rehmannia 8 base; clears Heat and cools Blood, clears deficiency Heat, and counterbalances the mildly warming nature of Shan Zhu Yu
- Ze Xie (Alisma plantago-aquatica) - Water plantain rhizome: From the Rehmannia 8 base; drains Damp and clears Heat through promotion of urination, supports kidney and bladder function, and prevents the tonic herbs from becoming too cloying
- Fu Ling (Poria cocos) - Poria mushroom: From the Rehmannia 8 base; drains Damp and strengthens the Spleen, counterbalances Shan Yao, supports fluid metabolism, and calms the Shen
- Huang Qi (Astragalus membranaceus) - Astragalus root: A key addition distinguishing Rehmannia 14; strongly tonifies Spleen and Lung Qi, supports immune function and Wei Qi, and addresses the Qi deficiency component absent in Rehmannia 8

- Bai Shao Yao (Paeonia lactiflora) - White peony root: A key addition distinguishing Rehmannia 14; nourishes Blood and Yin, softens the Liver, and moderates the warming properties of Fu Zi and Gui Zhi to prevent excessive Heat generation

- Zhi Mu (Anemarrhena asphodeloides) - Anemarrhena rhizome: A key addition distinguishing Rehmannia 14; clears Heat and nourishes Yin, addresses deficiency Heat and dryness in the Lung and Kidney systems, and works with Huang Bai as the classic Zhi Mu-Huang Bai pair to clear deficiency Fire
Potential Drug Interactions
Rehmannia 14 contains potent Yang-warming herbs and Qi tonics, including Fu Zi (prepared aconite) and Huang Qi (astragalus), which may affect cardiac function, immune modulation, and drug metabolism. This formula may also cause a positive drug test result. Pets on prescription medications should use this formula under veterinary supervision, as research on herb-drug interactions in dogs and cats remains limited.
Medication categories warranting extra caution include cardiac medications, immunosuppressive drugs, diuretics, hormone or thyroid therapies, and pets managing multiple concurrent prescriptions. Do not use during pregnancy and do not administer to animals prior to racing or competition. Your veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

Frequently Asked Questions
What conditions is Rehmannia 14 used for in TCVM?
Rehmannia 14 is indicated in TCVM for complex deficiency patterns involving simultaneous Yin, Qi, and Yang deficiency. Holistic veterinarians frequently recommend it for dogs, cats, and horses with endocrine conditions such as Cushing's disease, Addison's disease, hypothyroidism, or diabetes, as well as aging animals with mixed deficiency signs including fatigue, dryness, heat or cold intolerance, and immune dysregulation. Do not use during pregnancy.
How does Rehmannia 14 differ from Rehmannia 6 and Rehmannia 8?
Rehmannia 6 (Liu Wei Di Huang Wan) nourishes Kidney Yin only. Rehmannia 8 (Jin Gui Shen Qi Wan) adds Fu Zi and Gui Zhi to address Kidney Yang deficiency alongside Yin. Rehmannia 14 further expands the formula with Qi tonics (Huang Qi, Wu Wei Zi), additional Yin-nourishing herbs (Mai Men Dong, Bai Shao Yao), and Heat-clearing herbs (Huang Bai, Zhi Mu) to address the full spectrum of Yin-Qi-Yang deficiency, making it particularly suited for complex endocrine and immune patterns. Your authorizing veterinarian will determine which formula best matches your pet's TCVM pattern.
How is Rehmannia 14 administered, and what are the dosing guidelines?
Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance. For the 90g concentrated powder, the dose for dogs and cats is 0.1g to 0.25g per 10 to 20 lbs twice daily; the small scoop holds approximately 0.4g. For horses using the concentrated powder, the standard dose is 3g (approximately 2 large scoops) twice daily; the large scoop holds approximately 1.5g. For 0.5g concentrated capsules, the guideline is one capsule per 20 to 40 lbs of body weight twice daily. For small dogs and cats under 10 lbs, one 0.2g capsule once daily. Your authorizing veterinarian confirms Teapill dosing. Do not use during pregnancy, and do not administer to animals prior to racing or competition as this formula may cause a positive drug test result. Use for up to 3 months as directed.
How long does it take to see results with Rehmannia 14?
Response time varies depending on the severity and chronicity of the deficiency pattern. Many pet owners begin to notice improvements in energy, coat quality, thirst, urination patterns, and overall vitality within 4 to 8 weeks of consistent use. We recommend using this formula for up to 3 months. Regular follow-up with your holistic veterinarian is recommended to monitor progress, reassess the TCVM pattern, and review laboratory results as needed.
