The Essential Equine Tea-Pro Wound Spray contains all natural ingredients. It contains no alcohol and is non stinging. This spray is ant-microbial (tea tree oil). It stimulates epithelial growth or skin closure (goldenseal) and it helps to remove exudates from wounds for more rapid healing (comfrey). It can be used directly in open and deep wounds, including puncture wounds, and prevents the growth of proud flesh and allows for an even bed of granulation tissue and healing.
