Skin conditions are some of the most common disorders that a pet may suffer. And in many cases, the condition of a pet’s skin is an indicator of their overall health. It is very important, therefore, to pay close attention when a pet exhibits signs of having a skin issue, such as excessive biting, scratching, or licking of a particular area.

There are many reasons why pets have skin problems. Some common sources include pests like fleas and ticks, environmental allergens, excessive scratching, food allergies, or even drug allergies. Whatever the reason, Chinese herbal medicine can help.

A good herbal formula to treat general skin conditions that Western Medicine terms dermatitis or urticaria is Xiao Feng San (Eliminate Wind Powder). According to Traditional Chinese Medicine, itchy and red skin abrasions over large parts of the body may be due to wind-heat or wind-dampness attacking the skin and muscle layers of the body. This disharmony can lead to skin rashes, dermatitis, severe itching, and fluid leakage. To treat this condition, one must dispel wind and dampness, clear heat, and cool the blood.

The following details the uses of Xiao Feng San (Eliminate Wind Powder) and how it can help your pet.

Explanation

Xiao Feng San (Eliminate Wind Powder) treats wind-dampness and wind-heat attacking the skin and muscle layers of the body, giving rise to skin rashes, dermatitis, severe itching, and leakage of fluids. The treatment approach for this syndrome is to dispel wind and dampness, clear heat, and cool the blood.

Jing Jie (Herba Schizonepetae), Fang Feng (Radix Saposhnikoviae), Chan Tui (Periostracum Cicadae), and Niu Bang Zi (Fructus Arctii) are the chief herbs that dispel wind from the exterior. Cang Zhu (Rhizoma Atractylodis) strengthens the Spleen and dries dampness. Ku Shen (Radix Sophorae Flavescentis) clears heat and dries dampness. Mu Tong (Caulis Akebiae) eliminates damp-heat through diuresis. Shi Gao (Gypsum Fibrosum) and Zhi Mu (Rhizoma Anemarrhenae) clear heat and sedate fire. Since wind-dampness and wind-heat may injure yin and blood, Di Huang (Radix Rehmanniae), Dang Gui (Radix Angelicae Sinensis), and Hei Zhi Ma (Semen Sesami Nigrum) are added to tonify the blood, nourish yin, and moisten dryness. Gan Cao (Radix et Rhizoma Glycyrrhizae) clears heat, eliminates toxins, and harmonizes the formula.

Comments
From a traditional Chinese medical perspective, Xiao Feng San treats dermatological disorders caused by wind-dampness and wind-heat attacking the skin. In terms of anatomy and physiology, such dermatological disorders are similar in location and manifestation to allergic or hypersensitivity reactions. Clinical applications include skin rashes and hives, itching and dermatitis secondary to environmental allergens, fleas, drugs, chemicals, or food. Xiao Feng San can also be combined with other formulas for additional clinical applications:

  • In cases of wind-heat that has progressed to pyoderma, Xiao Feng San can be combined with Yin Qiao San (Honeysuckle and Forsythia Powder).
  • For pyoderma caused by internally generated heat in the Liver, it can be combined with Long Dan Xie Gan Tang (Gentiana Decoction to Drain the Liver).
  • It can be combined with Dang Gui Yin Zi (Tangkuei Decoction) to treat chronic dermatitis cases in which the underlying, chronic yin and blood deficiencies have predisposed the animal to external wind invasion, especially during seasonal allergy times in the spring and fall.

In addition to using Xiao Feng San internally to relieve itching, Ku Shen (Radix Sophorae Flavescentis) and She Chuang Zi (Fructus Cnidii) can be used as an external wash to enhance the overall effects. Furthermore, administration of a topical application of Ma Chi Xian (Herba Portulacae) as an herbal paste also increases the overall effectiveness of Xiao Feng San.
