Chinese physicians working from the beginning of the Ming dynasty (1368-1644 C.E.) through the Qing dynasty (1644-1911 C.E.) developed what became known as the Pattern of Four Levels (wei-qi-ying-xue bian-zheng). Taking from the Nei Jing they described four sequential physiological entities/scenes, each one of them represents a different distinct depth of body’s pathology.
Level 1 is called the Wei Qi (wei-fen-zheng) Pattern. It occurs at the first depth of the body. In the skin, it is the Level above the epidermis (fur coat, flora of bacteria, fungi etc on the skin, sweat, sebum, IgA from animal’s saliva etc) and goes down through the epidermis, through different layers from outside to inside: stratum corneum, stratum granulosum, up to the upper part of stratum spinosum.
Level 2 is called the Qi (qi-fen-zheng) Pattern. It occurs at the second depth of the body. In the skin, it is the Level of epidermal basal layer (stratum basale) with some portion of lower part of stratum spinosum, both referred as stratum germinativum or Malpighian layer.
Level 3 is called the Ying (ying-fen-zheng) Pattern. It occurs at the uppermost layer of the dermis and extends down through its deeper layers, excluding the lower third of the dermis. The word ying describes the Nutritive aspect of Qi that is associated with Blood and mainly with the extra-cellular fluid.
Level 4 is called the Xue [Blood] (xue-fen-zheng) Pattern. It is the final and deepest of the Four Levels. In the skin, it is the lower part of the dermis, mainly in the lower blood plexuses, and in the hypodermis.
According to this specific concept, one should look on animal’s skin and ask: “At what Level is the lesion located?”
Acute moist dermatitis due to flea bites [“hot spot”] might be in the Wei Qi Level. In chronic ulcerative dermatitis due to immunological condition, like discoid lupus erythematosus, the lesion has entered deep into the Xue Level. In lichenification and hyperpigmentation, the lesion might be in the Ying Level.
Identification of the lesion’s Level can be found by a simple observation without any specific advanced tools. One may use histological preparations or other advanced methods to assist in making the determination of the lesion’s location.
I urge you to put your Chinese herbal remedies for skin conditions into transdermal gel or foam. Application of herbs in this way dramatically increases clinical success rates in skin diseases.
Advantages of using transdermal gels or foam:
Disadvantages of using transdermal gels or foam:
Note – gel should be protected from sunlight and heat, and out of reach of children and animals.
