Fantastic Medicinal Bodily Product

"Dragon liver can cure a cold, dragon powder grows hair, with dragon blood you'll never grow old.
Dragon cartilage keeps you thin, dragon fat is for burns, a dragon tear will clear up your skin."

— Pete's Dragon (1977), "Every Little Piece"

A creature, or an entire species, possesses remarkable healing abilities due to a particular bodily product. Usually the product is a fluid, likely saliva or blood. In various media, for example, vampire saliva is a natural coagulant and helps the puncture wounds close (incidentally making it a handy tool for maintaining The Masquerade). However, it could be any other bodily product, such as urine or bone. The medicinal properties of the product can also range from healing wounds to curing illnesses to bestowing invincibility. Very often, the healing factor only works on other species, not their own, though this is not a strict requirement for the trope.

Psionic powers used to heal or take away pain do not count under this; they are examples of the Empathic Healer.

Sub-Trope of Bizarre Alien Biology. May be a Panacea.

Compare Swiss-Army Tears and Healing Hands for other body products/parts that heal. If someone tries to profit from these healing body parts through captive monsters, see Monster Organ Trafficking. If the product in question is a waste product or a secretion, see Solid Gold Poop. If the product is repugnant, such as snot or pee, it could be used in a Revolting Rescue. See also Crafted from Animals.

• In Bleach, Nel's saliva/drool is capable of healing people from near death.
• In Blue Ramun, the blood of members of the Blue Ramun tribe can cure nearly all diseases, neutralize most poisons, and accelerate the healing of wounds. The healing powers inherent in the Blue People are explicitly stated to be one of the most potent magical forces in the entirety of the low-magic setting — which is why the Garicalege traffics in stolen blood of the Blue Ramun tribe, and why Dr. Zai murdered his fellow Blue tribe members and attempted to craft medicine from their hearts.
• In Miss Kobayashi's Dragon Maid, Tohru claims that dragon saliva has healing properties (on top of being able to wash delicate clothing), but Ilulu says that she's just looking for an excuse to lick Kobayashi.

• In trash., the blood of Hiroshi gives those treated with it a Healing Factor but sends people who use it too much into a berserker state in which they can no longer tell friend from foe, which happens to Soo-in and ultimately Francesca herself.
• Invoked by the vampire-like Chui in 3×3 Eyes, who seems to firmly believe that drinking the blood of Pai, the last Sanzhiyan (Triclop) will make him immortal. However, it's implied by Parvati that this is a mere rumor and not an actual fact.

Audio Plays

• In the Big Finish Doctor Who audio play The Bride of Peladon, the Doctor uses his own blood as an antidote, because he'd been attacked and injured badly enough to activate his souped-up Time Lord immune system, releasing special platelets to heal his injuries instead of having to regenerate, effectively turning his blood (temporarily) into a panacea.

Comic Books

• In Brat Pack, True-Man's blood is capable of curing HIV and bestowing a healing factor.
• Judge Dredd has a peaceful and harmless intelligent alien race called Stookies — who just happen to have glands in their bodies that make humans appear younger when they eat them. Since the glands can only be harvested by killing the Stookie, this is desperately unethical and immoral, even by Dredd's Crapsack World standards. However, due to Fantastic Racism, it's only a ten-year sentence instead of fifteen to life for murder as alien lives are worth less than humans'.
• In one issue of the Futurama comic book, Fry's cold infects the citizens of New New York, and once a person gets better they cough up a gelatinous mass that comes together to create a giant Blob Monster. Leela becomes afflicted too, but after her illness goes away, which included stripping naked and living with a pack of squirrels for a few days, she shows off a giant white blood cell on a leash, and Professor Farnsworth deduces that her mutated immune system is what created the large white cell, and they go to the sewers to infect the mutants. When they spit out their giant white cells, the two blobs meet, and destroy each other, saving the city.

  • The Incredible Hulk: In an issue from the early 1990s, Jim Wilson, a former teen sidekick of the Hulk, asks him for a transfusion because he's dying of AIDS and thinks that the Hulk's irradiated blood makes him immune to HIV and will cure him.

  • X-Force (Milligan & Allred): At one point the team is deployed to Central America to kidnap a boy whose mutant powers make him a living pharmacy. Mr. Sensitive revolts against the team's financial backers after learning that they intended to harvest the kid's organs and bodily fluids to make new drugs.
