In Part 5 of The Witch's Brew, Dr. Kitt explores Long Yi — 'Dragon's Clothes,' the naturally shed snake skin used in classical Chinese medicine — alongside elderberry, folklore's Witch Tree. Together they may help support itchy skin conditions, surface inflammation, sore throats, and seasonal immune resilience.

Halloween and Chinese herbal medicine share a taste for the dramatic. This series explores TCM herbs that read like spell ingredients — because in many respects, they are. Welcome to Part 5 of The Witch's Brew.
This week the focus is Long Yi (龙衣) — "Dragon's Clothes," the naturally shed skin of snakes — paired with elderberry, the dark, folklore-soaked fruit of the elder tree. Both have been used in traditional healing for centuries. Together, they address what classical TCM calls the body's exterior layer: the skin, eyes, throat, and the outermost line of seasonal immune defense.

Long Yi (龙衣): Dragon's Clothes — The Shed Snake Skin Herb for Itchy Skin and Surface Inflammation
Long Yi, also written as She Tui (蛇蜕) or *Serpentis Pericarpium*, is the naturally shed epidermal skin of snakes — specifically species such as *Elaphe taeniura* and *Zaocys dhumnades*. The name "Dragon's Clothes" reflects the reverence classical Chinese medicine holds for the snake as a symbol of transformation: the animal sheds its outer layer entirely and emerges renewed. In TCM theory, Long Yi is used to help the human body do something similar — release accumulated Wind, Heat, and surface obstruction from the exterior tissues of the skin, eyes, and throat.
An important distinction: Long Yi (龙衣), also called She Tui (蛇蜕), is shed snake skin. Chan Tui (蝉蜕) is the shed exoskeleton of cicadas — a different herb entirely. Both address surface-layer conditions in TCM including skin rashes, hives, sore throats, and eye irritation, which makes confusion easy. They are not interchangeable. Long Yi comes from snakes; Chan Tui comes from cicadas. Each has its own processing methods and clinical profile.
What Long Yi May Help: Itchy Skin, Eczema, Hives, and Psoriasis
In TCM theory, Long Yi clears Wind and Heat from the body's surface. When Wind and Heat accumulate in the skin, the result is often intense itching, redness, and scaling — patterns that align with conditions such as eczema, hives, psoriasis, and scaly skin rashes. Long Yi has traditionally been used to help calm severe itching, support smooth skin regeneration, and address surface inflammatory patterns.
For patients in Sarasota navigating subtropical heat and humidity alongside seasonal allergen exposure, the TCM idea of surface heat driving skin reactivity is particularly relevant. As part of an individualized herbal formula, Long Yi has been used for the kind of persistent, treatment-resistant itching that can accompany systemic conditions like fibromyalgia or surface nerve sensitivity seen in neuropathy of the feet. Each case is assessed individually — pattern matters as much as diagnosis.
Sore Throats and Eye Cloudiness
Long Yi's reach extends beyond the skin. It has traditionally been applied in TCM formulas targeting superficial eye cloudiness such as pterygium, corneal spasm, and sore throats — all considered surface-layer conditions in classical theory. Just as the snake sheds the outermost layer to emerge clear, Long Yi may help clear obstructions at external portals like the eyes and throat.
Long Yi Preparation: Cruelty-Free and Carefully Processed
No snakes are harmed in the collection of Long Yi. These are naturally discarded, empty skins collected from wild shed cycles or regulated facilities. They are thoroughly cleaned and then processed — stir-baked with wine, baked with salt, or gently charred — to neutralize residual odor and enhance the herb's channel-penetrating properties. The finished material is ground into powder or added to boiled decoctions.

Elderberry (Sambucus nigra): The Witch Tree
The elder has been the witch's tree across European folklore for longer than written records can trace. The elder's protective spirit — *Hyldemoer*, the Elder Mother in Danish tradition — was said to guard the threshold between worlds. Elder twigs hung over doorways on Halloween night were believed to keep uninvited spirits out.
The Science Behind Elderberry's Immune Support
Elderberry's deep purple color comes from anthocyanins — potent antioxidants that have attracted scientific attention in recent decades. Research suggests elderberry extract may inhibit viral entry into cells, potentially supporting a reduction in the duration and severity of cold and flu. From a TCM perspective, elderberry tonifies Wei Qi — defensive energy — the same exterior layer Long Yi addresses from a surface tissue standpoint.
Elderberry for Chest Congestion and Respiratory Support
Beyond immune support, elderberry has traditionally been used as a natural expectorant to soothe chest and airway inflammation. For Sarasota patients whose migraines or tension headaches worsen during sinus congestion and illness, elderberry is a common and well-tolerated seasonal wellness measure worth discussing with a provider.
Raw Elderberry Safety Warning
Raw elderberries — and the leaves, stems, seeds, and bark of the elder plant — contain cyanogenic glycosides that can cause severe nausea and significant harm. All elderberry intended for consumption must be thoroughly cooked. Commercially prepared elderberry syrups and supplements use processed, cooked extract. Elderberry preparations containing honey should never be given to infants under one year of age due to the risk of infant botulism.

Long Yi and Elderberry Together: Shedding the Old, Defending the New
Long Yi helps the surface shed accumulated Heat, Wind, and stagnation — freeing the skin, eyes, and throat to function clearly. Elderberry defends that same boundary against seasonal invaders. Clear skin, open throat, resilient immunity — in TCM, these are not separate concerns. They are expressions of the same healthy exterior.

Frequently Asked Questions
How is Long Yi prepared for medicinal use?
Long Yi is first thoroughly cleaned and washed. It is then processed using classical methods: stir-baked with wine to enhance channel-penetrating properties, baked with salt to modify its directional action, or gently charred to neutralize odor. Each processing method alters the herb's clinical emphasis in ways a trained practitioner accounts for when formulating. The finished material is ground into fine powder or added to decoctions. Raw, unprocessed shed skins are not used medicinally.
What is the difference between Long Yi and Chan Tui?
Long Yi (龙衣), also written She Tui (蛇蜕), is the shed epidermal skin of snakes. Chan Tui (蝉蜕) is the shed exoskeleton of cicadas — a different creature entirely. Both herbs address surface-layer conditions in TCM, which makes confusion easy to understand. However, they are distinct substances from different animals, processed differently, with different clinical profiles. They are not interchangeable, and a qualified TCM practitioner distinguishes between them based on the patient's full pattern presentation.
Are raw elderberries safe to eat?
No. Raw elderberries contain cyanogenic glycosides that convert to hydrogen cyanide during digestion. Consuming raw elderberries or raw plant material from the elder can cause severe nausea, vomiting, and worse. Elderberry must always be thoroughly cooked before consumption. Commercially available elderberry syrups and supplements use properly processed extract and are generally safe when used as directed.
Can children take elderberry?
Cooked elderberry preparations are widely used as a pediatric seasonal immune support option and are generally considered safe for children in age-appropriate amounts. Elderberry products containing honey should never be given to infants under one year of age due to the risk of infant botulism. Consult a pediatric healthcare provider before giving any supplement to a young child.
What is the difference between Long Yi and Wu She?
Both are snake-derived TCM herbs but work at different levels of the body. Long Yi uses only the naturally shed, empty skin and is directed at surface conditions: skin rashes, itching, sore throats, and superficial eye cloudiness. Wu She (乌蛇, black-striped snake) uses the whole dried snake body and is directed at deeper conditions: persistent joint pain, nerve pain, and stubborn obstruction in the channels that surface-layer herbs cannot reach.
