Kan Essentials Dry Derma Relief (Si Wu Xiao Feng Yin, Four Materials Eliminate Wind Decoction) is a Traditional Chinese Veterinary Medicine (TCVM) herbal formula formulated to nourish Blood, nourish Liver Blood, and subdue Wind Heat invasion to support healthy skin, coat, and emotional wellbeing. Recommended by holistic veterinarians, this formula is directly based on Si Wu Xiao Feng Yin, first described by Wu Qian in Golden Mirror of the Medical Tradition in 1742. It is most commonly given to dogs because of their apparent predisposition to Liver Blood deficiency. Available in liquid and tablet forms. Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance.

Dry Derma Relief is built on a modified Four Substances (Si Wu Tang) Blood-tonifying core, with Chi Shao substituted for Bai Shao to add Blood-cooling effects, combined with five Wind-expelling herbs and Bupleurum root to address Wind Heat invasion and Liver Qi stagnation simultaneously.
Dry Derma Relief contains several potent Chinese herbs, including Blood-nourishing, Blood-cooling, and Wind-expelling herbs with known dermatological, cardiovascular, and immune-modulating activity. Because herb-drug interaction research in dogs and cats is limited, pets taking prescription medications should use this formula under veterinary supervision. Avoid use during pregnancy and use with caution in animals with Wind Damp Heat.
Extra caution may be appropriate for pets receiving anticoagulant or antiplatelet medications, dermatological medications, immunosuppressive drugs, or multiple prescription medications. Your veterinarian can determine whether Dry Derma Relief is appropriate based on your pet's condition, medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Dry Derma Relief (Si Wu Xiao Feng Yin) is traditionally used to nourish Blood, nourish Liver Blood, and subdue Wind Heat invasion. It is indicated for patterns of Liver Blood deficiency with Wind Heat invasion in the skin, most commonly used in dogs to support healthy skin, coat, and emotional calm.
Dry Derma Relief is available in liquid extract (1 oz, 4 oz, or 8 oz) or 500mg tablets (60, 120, or 300 count). Liquid can be mixed into food or administered directly; tablets can be given directly or hidden in food. Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance.
Results vary by individual and the severity of the pattern. Some animals may show improvement in skin comfort and coat quality relatively quickly, while those with more chronic or established Liver Blood deficiency and Wind Heat patterns may require several weeks of consistent use. Your authorizing veterinarian can help set appropriate expectations based on your pet's TCVM diagnosis.
Always consult your veterinarian before combining Dry Derma Relief with other medications or supplements. Your authorizing veterinarian will monitor for potential interactions through routine lab work and diagnostic testing. Key interactions to discuss include anticoagulants, dermatological medications, and immunosuppressive drugs. See the Potential Drug Interactions section above for details.
