6 Unusual Uses of Animal Waste Including Kopi Luwak

Ever wondered why a cup of coffee can cost as much as a nice dinner—or why ancient Egyptians might have used crocodile poop for birth control? From luxury drinks to ancient medicine, humans have found bizarre but real uses for animal excrement across history. This isn’t about novelty: it’s about how certain animal waste products have genuinely impacted food, scent, health, and even fertility practices around the world.

Kopi Luwak, or civet coffee, fetches between $300 and $800 per pound and is among the most expensive coffees globally, thanks to a unique digestive process that alters the beans’ flavor.

1. Kopi Luwak: The World’s Most Expensive Coffee

Kopi Luwak, also known as civet coffee, hails mainly from Indonesia and is among the priciest coffees in the world. In Hong Kong, a single cup often costs $200–$300 and is available only in top-tier hotels. Prices per pound range from $300 to $800. Originally despised by farmers, this coffee is made from beans eaten and excreted by the Asian palm civet—locally called a “musang” or “civet cat.”

The civet selects only the ripest, sweetest coffee cherries. Inside its digestive tract, the fruit’s flesh is digested, but the hard coffee bean passes through intact. The digestion process reduces bitter proteins, resulting in a smoother, less acidic cup with a rounded, full-bodied flavor. Though once a curiosity, it’s now highly sought after, often more than traditional Jamaican Blue Mountain coffee.

2. Animal-Derived Perfumes: Ambergris in Fragrance

Ambergris, a rare substance from the sperm whale, is a key ingredient in high-end perfumes. Comprising around 25% ambrein, it acts as a fixative, helping scents linger on skin. Initially thought to be dragon spit, it’s actually formed when sperm whales consume squid and octopus. Indigestible beaks irritate the whale’s gut, prompting it to secrete a fatty substance that coats the sharp objects. This eventually forms ambergris, expelled as fecal matter or vomit.

Fresh ambergris smells foul, akin to dung, but over time—through saltwater, sunlight, and air—it develops a sweet, earthy, and complex aroma. It’s also used in traditional Chinese medicine for its alleged benefits in clearing phlegm and improving circulation.

3. How Animal Waste Helped Save a Tree Species

The extinct dodo bird played an essential role in the germination of the tambalacoque tree (often associated with the dodo’s relative, the calvaria or Sideroxylon grandiflorum, though sometimes misidentified as the dodo’s tree). On Mauritius, before the dodo disappeared around 1693, its digestive system helped scarify the tough seeds of the tambalacoque tree, enabling them to sprout. Once the dodo died out, the tree faced reproductive challenges. By the 1980s, only 13 specimens remained. Scientists discovered that introducing the seeds to turkeys—a stand-in for the dodo’s digestive process—allowed the trees to regenerate.

4. Traditional Medicine: Animal Poop as Herbal Remedies

Animal feces have long been used in Traditional Chinese Medicine (TCM). Historical texts, including Zhang Zhongjing’s “Essentials from the Golden Cabinet” from the Eastern Han Dynasty and Li Shizhen’s “Compendium of Materia Medica,” list dozens of animal waste-based remedies. Over 51 animal-derived substances are documented, involving 32 species including mammals, birds, and humans.

Examples include:

• Chicken droppings for childhood ailments
• Sheep dung for diarrhea
• Donkey dung for menstrual disorders
• Camel dung for nosebleeds
• Lion dung to treat blood stasis and parasites
• Tiger dung for hemorrhoids
• Cat dung for measles complications
• Wolf dung for bone obstructions
• Monkey dung for infant convulsions
• Pigeon dung for lymphatic abscesses
• Sparrow droppings for hernias and eye issues
• Owl and bat droppings under names like (night-bright sand) and (moon-gaze sand) for vision and parasitic infections
• Flying squirrel dung for detoxifying bites and regulating blood flow

5. Ancient Contraception: Crocodile Dung in Egypt

Ancient Egyptian medical texts describe one of the earliest known contraceptive methods: a pessary or vaginal suppository made from crocodile dung, mixed with honey, milk, frankincense, and sometimes aloe. This mixture, inserted into the vagina or cervix, was believed to prevent pregnancy. While primitive, the acidity of crocodile dung may have offered some spermicidal effect. Though effective in theory, the strong odor led to its discontinuation. This method counts among humanity’s first recorded attempts at chemical contraception.

6. Cleaning Products: From Cow Dung Toothpaste to Camel Urine Shampoo

In Tunisia, the Berber people traditionally used hardened cow dung mixed with spices and minerals as a tooth-cleaning powder, applied with a mint stem. The abrasive blend helped clean teeth, prevent gum disease, and whiten enamel—especially useful for meat-heavy diets. In North African deserts, the Bedouin people used camel urine as shampoo. Rich in ammonia, it was valued for killing lice and was said to leave hair shiny. It was also used as a face wash for smoother skin. This practice, with roots in ancient Egypt, even allegedly included Cleopatra using lion urine for her hair.

Frequently Asked Questions

What makes Kopi Luwak coffee so special and expensive?

Kopi Luwak is made from coffee beans eaten and excreted by the Asian palm civet. Only the ripest cherries are selected. The civet’s digestion removes the fruit’s flesh but leaves the bean intact. Enzymes in the civet’s gut break down bitter proteins, resulting in a smoother, less acidic cup with enhanced body and sweetness. Its rarity and unique processing contribute to prices ranging from $300 to $800 per pound.

What is ambergris and why is it used in perfume?

Ambergris is a waxy substance produced in the digestive system of sperm whales. It forms around indigestible squid beaks and, after being expelled, ages to develop a sweet, earthy, and musky aroma. It acts as a fixative in perfumes, helping scents last longer on the skin. Originally known as “floating gold,” it was once thought to be dragon saliva.

How did the dodo bird help the tambalacoque tree reproduce?

The extinct dodo bird ate the tough fruits of the tambalacoque tree, and its digestive system scarified the hard seeds, allowing them to germinate. After the dodo’s extinction, the tree struggled to reproduce. In the 1980s, scientists found that using turkeys to mimic the dodo’s digestive breakdown allowed the tree seeds to sprout again, saving the species from extinction.

Which animal feces were used in ancient Chinese medicine?

Over 51 animal-derived feces were recorded in classical Chinese medical texts, including chicken, sheep, donkey, camel, lion, tiger, cat, wolf, monkey, pigeon, and bat droppings. These were used to treat conditions ranging from childhood illnesses and menstrual disorders to parasites, vision problems, and blood stasis. Each type was assigned traditional medicinal properties and poetic names like (moon-gaze sand) for bat droppings.

How was crocodile dung used as contraception in ancient Egypt?

Ancient Egyptians created a contraceptive pessary from crocodile dung mixed with honey, milk, frankincense, and aloe. This mixture was inserted into the vagina or cervix. The acidity of the dung may have had a spermicidal effect, offering limited contraceptive protection. Despite possible efficacy, the strong smell led to its discontinuation.

What unusual cleaning products have been made from animal waste?

In Tunisia, hardened cow dung mixed with spices was used as toothpaste to clean teeth and prevent gum disease. In the Sahara, camel urine was used as shampoo due to its ammonia content, which killed lice and left hair shiny. Both practices emerged in response to harsh climates and limited fresh water, and were culturally adopted for oral and dermatological hygiene.
