Every October, witches in stories reach for the darkest, strangest ingredients they can find. Chinese imperial physicians were centuries ahead of them. Welcome to Part 2 of our seven-part series on the most hauntingly named herbs in Traditional Chinese Medicine — two ingredients that look like they belong in a gothic novel but have been used for real clinical purposes for over a thousand years.
This installment features Xue Jie (血竭), the crimson resin known as Dragon's Blood, and Chan Tui (蝉蜕), the translucent ghost-shell a cicada leaves behind when it sheds its exoskeleton. Together they address conditions ranging from bruising and blood stasis to sore throats, hoarse voice, and itchy skin rash.

Xue Jie (Dragon's Blood Resin): Wound Healing and Blood Stasis
What Is Dragon's Blood Resin?
Xue Jie — translated literally as "Blood Resin" — is the deep ruby-red sap extracted from specific *Dracaena* palm species. Dried and powdered, it looks like crushed garnets. The name "Dragon's Blood" captures the way the resin bleeds red from the bark, though the word "Dragon" was dropped from its formal pharmacopoeial name over time. It is also found in Western literature as *Resina Draconis*.
For practitioners incorporating evidence-informed herbal medicine into care plans in Sarasota, Xue Jie represents one of the oldest-documented wound-healing substances in the TCM pharmacopoeia. Its documented use spans from Canary Island traditional medicine to Chinese martial arts lineages — and it has recently found its way into high-end skincare for its documented anti-inflammatory and skin-repairing properties.
How TCM Uses Xue Jie for Bruising and Blood Stasis
In TCM, Xue Jie is classified as an herb that invigorates Blood, dispels stasis, and stops bleeding — a paradox that makes sense within the TCM framework. When Blood is "stuck" (a state called Blood stasis), circulation is impaired, pain intensifies, and tissue repair slows. Xue Jie is traditionally used to move stagnant Blood while simultaneously helping to seal damaged vessels.
Historically, this made it the go-to herb for severe trauma, deep bruising, bleeding wounds, and intense localized pain — conditions familiar to martial artists and soldiers. Patients dealing with post-knee replacement pain, post-hip replacement pain, or stubborn bruising around injured joints may find that their TCM practitioner considers a Blood stasis pattern and a formula containing Xue Jie as part of a broader treatment approach.
Preparation: Xue Jie is used as a topical powder applied directly to affected tissue, or taken internally in small encapsulated doses. It does not extract well through standard water decoction and is not typically simmered the way most TCM herbs are.
Historically, martial artists and field physicians used Xue Jie both externally and internally for traumatic injury, deep bruising, bleeding wounds, and intense localized pain. Its reputation was earned through direct, practical application across centuries. Today, Dragon's Blood also appears in high-end skincare formulations for its purported anti-inflammatory and skin-barrier-supporting properties — a rare crossover from the classical materia medica into mainstream cosmetics.
What Xue Jie May Be Used For
Traditional and contemporary herbal literature suggests Xue Jie may help support recovery from bruising and soft tissue trauma, help move Blood stagnation associated with chronic, fixed pain patterns, support wound healing as a topical application, and help quell localized pain and swelling following acute injury.
Patients managing chronic musculoskeletal pain patterns — such as those explored on our chronic low back pain and knee osteoarthritis condition pages — may find that Chinese herbal formulas incorporating Blood-moving herbs like Xue Jie are discussed as part of a broader integrative approach.

Chan Tui (蝉蜕): The Ghostly Cicada Shell for Sore Throat, Skin Rash, and Hoarse Voice
What Is Chan Tui — and How Is It Different from Long Yi?
This distinction is worth making clearly. Chan Tui (蝉蜕) is the translucent, papery outer exoskeleton of the cicada nymph. Every summer, cicada nymphs crawl from underground, climb a tree trunk, and shed their entire outer shell as they transform into adult cicadas. What clings to the bark afterward — hollow, weightless, and ghost-like — is Chan Tui. It is collected after the cicada has fully departed. Entirely cruelty-free.
Long Yi (龙衣) — literally "Dragon's Clothes" — is shed *snake skin*, collected after a snake molts its scales. Long Yi is a heavier herb used for chronic, stubborn, scaly skin conditions and deeper persistent itching. Both herbs share the metaphor of "shedding," but they are completely different substances with different therapeutic targets, different preparation methods, and different clinical applications. For a full discussion of Long Yi, see Part 5 of this series.
How TCM Uses Chan Tui for Sore Throat, Hoarse Voice, and Skin Rash
The TCM logic of Chan Tui flows from the image of transformation: the cicada casts off its exterior to emerge renewed. Clinically, practitioners use this "venting and releasing" energy to help the body clear conditions affecting the exterior — skin, throat, and upper nervous system.
For sore throat and hoarse voice: Chan Tui clears Wind-Heat from the lungs and throat. When a person loses their voice — from viral illness, seasonal exposure, or overuse — TCM may diagnose Wind-Heat lodged in the throat channels. Chan Tui may help relieve throat inflammation, calm hoarseness, and soothe the ticklish, lingering cough that often accompanies these episodes.
For itchy skin rash and hives: When allergic responses or fevers produce an itchy rash — particularly early-stage hives or urticaria — TCM describes this as unexpelled Wind-Heat trapped at the body's surface. Chan Tui is traditionally used to help the body "vent" these conditions outward. Patients managing fibromyalgia with heightened skin sensitivity, or those experiencing diffuse skin reactivity alongside neuropathy in the feet, may encounter Chan Tui as part of a broader herbal formula.
For pediatric agitation from fever: Chan Tui's light, venting nature has made it a longstanding ingredient in pediatric formulas addressing night terrors and restless twitching associated with febrile illness.
Preparation: Chan Tui is lightly crushed and simmered in a standard herbal decoction, frequently paired with mint (Bo He) for throat applications, or combined with licorice root (Gan Cao) for skin conditions.
Shellfish allergy note: Chan Tui contains chitin — the same structural polymer found in crustacean shells. Patients with a severe shellfish allergy should discuss this with their acupuncture physician before using Chan Tui in any formula.

Frequently Asked Questions
Why is Dragon's Blood called Xue Jie and not Long Xue?
"Dragon's Blood" is the widely recognized common name in English-speaking markets and Western herbal literature, where it is also catalogued as *Resina Draconis*. In the formal Chinese pharmacopoeia, the herb was renamed Xue Jie — "Blood Resin" — as part of standardization efforts that favored descriptive botanical language. If you search TCM databases or academic papers, you may encounter any of these three names referring to the same substance.
What is the difference between Chan Tui and Long Yi?
They are entirely different herbs that share only the metaphor of shedding. Chan Tui (蝉蜕) is the shed outer exoskeleton of the cicada — translucent, lightweight, and papery — with primary clinical applications in the upper body: throat irritation, hoarse voice, early-stage skin rashes, and Wind-Heat patterns. Long Yi (龙衣) is shed snake skin — heavier in nature, oriented toward chronic, stubborn, scaly skin conditions and deeper persistent itching. Part 5 of this series covers Long Yi in full detail.
How is Xue Jie (Dragon's Blood resin) typically taken?
Xue Jie is most commonly used as a fine powder applied topically to bruised or wounded tissue, or taken internally in small encapsulated doses for blood stasis conditions. It is not typically simmered in a standard herbal decoction because its active resins do not extract efficiently through water-based preparation. A licensed TCM practitioner will determine the appropriate delivery method based on your specific diagnosis and treatment plan.
How is Chan Tui typically prepared?
Chan Tui is lightly crushed and simmered as part of an herbal decoction alongside other herbs. For throat applications it is frequently paired with mint (Bo He); for skin-related formulas it is often combined with licorice root (Gan Cao). It is rarely used as a standalone herb.
Is Chan Tui safe for people with shellfish allergies?
Chan Tui contains chitin, the same structural compound found in crustacean shells. Patients with a documented severe shellfish allergy should discuss this with their acupuncture physician before using Chan Tui in any formula. A qualified practitioner can assess your allergy history and identify alternative herbs that accomplish similar therapeutic goals without the concern.
