Frequently Asked Questions
What conditions is Rehmannia 14 used for in TCVM?
In Traditional Chinese Veterinary Medicine, Rehmannia 14 is indicated for complex deficiency patterns involving simultaneous Yin, Qi, and Yang deficiency. It is commonly recommended 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.
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 Yang-warming herbs to address Kidney Yang deficiency alongside Yin. Rehmannia 14 further expands the formula with Qi tonics (Huang Qi), additional Yin-nourishing herbs (Mai Men Dong, Wu Wei Zi), 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 this formula administered to dogs, cats, and horses?
Mix the concentrated powder directly into wet or dry food at each meal using the included double-sided scoop. You can give capsules whole or open them and sprinkle the contents over food. You can hide Teapills in food or a soft treat. Dosing is based on species and body weight; your authorizing veterinarian will confirm the correct dose and schedule. Do not use during pregnancy, and do not administer prior to racing or competition, as this formula may cause a positive drug test result.
How long does it take to see results with Rehmannia 14?
Results vary depending on the severity and chronicity of the condition. 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. This formula is recommended for use up to 3 months; your veterinarian will guide reassessment intervals based on your pet's response and laboratory results.
