What is Dragon's Blood (Croton lechleri)?

Dragon's Blood is the striking dark-red latex sap harvested from Croton lechleri, a tree native to the Amazon basin of South America. Indigenous peoples of Peru, Ecuador, Colombia, and Bolivia have used it for generations as a go-to remedy for cuts, wounds, stomach troubles, and infections. Its deep color and thick texture gave rise to the evocative name 'Sangre de Drago' — dragon's blood.

How does Dragon's Blood (Croton lechleri) work?

Dragon's Blood works through several pathways at once. Its key compound, crofelemer, reduces fluid secretion in the intestinal lining, which directly curbs diarrhea. Topically, the alkaloid taspine stimulates wound healing by encouraging skin cells to migrate and close over injuries. The resin also contains powerful antioxidant proanthocyanidins that calm inflammation and help protect tissues from damage.

What forms does Dragon's Blood (Croton lechleri) come in?

The raw liquid resin can be applied directly to wounds or taken orally as drops. Capsule and tablet forms are used for gut-related conditions. In clinical settings, crofelemer is available as a pharmaceutical tablet (Mytesi/Crofelemer). Traditional Amazonian use typically involves applying a few drops of the raw sap directly to cuts or taking a small amount orally for stomach issues.

Where it comes from:

Dragon's Blood has been a cornerstone of Amazonian folk medicine for at least several hundred years, documented by ethnobotanists as one of the most widely used medicinal plants in the region. It gained scientific attention in the 1980s and 1990s when researchers isolated its key compounds, eventually leading to the pharmaceutical development of crofelemer, which received FDA approval in 2012 for a specific form of diarrhea — making it a rare example of a traditional plant medicine becoming a modern approved drug.

What does Dragon's Blood (Croton lechleri) help with?

• Diarrhea and traveler's diarrhea: Dragon's Blood reduces the excessive fluid secretion that drives watery diarrhea by acting directly on the gut lining. Its active compound crofelemer blocks the channels that cause the gut to dump fluids, helping stools firm up quickly without completely stopping gut movement.
• HIV-related diarrhea: The crofelemer extract from Dragon's Blood is the active ingredient in the FDA-approved drug Mytesi, specifically indicated for non-infectious diarrhea in HIV patients on antiretroviral therapy. This is the most clinically validated use of this plant's compounds.
• Wound healing and skin cuts: Applied topically, Dragon's Blood sap forms a protective film over wounds and actively stimulates skin cells to close the injury. The alkaloid taspine has shown wound-contracting properties, and the resin's antimicrobial compounds help keep healing wounds clean.
• Gut inflammation and leaky gut: The proanthocyanidins in Dragon's Blood have anti-inflammatory effects in the gut lining, helping to calm irritation and support the integrity of the intestinal barrier. This makes it potentially useful for conditions where the gut wall is inflamed or overly permeable.
• Mouth sores and ulcers: Dragon's Blood has traditionally been applied to mouth ulcers and inflamed gums due to its antimicrobial and tissue-protective properties. Some small studies suggest it can speed up healing of oral sores when applied topically.
• Stomach ulcers: Traditional use and early research suggest Dragon's Blood may help protect the stomach lining and support ulcer healing, likely due to its anti-inflammatory and antimicrobial activity against H. pylori, a common ulcer-causing bacterium.
• Skin inflammation and rashes: Applied to the skin, the sap's antioxidant and anti-inflammatory compounds can help soothe irritated, inflamed, or infected skin. Indigenous use for insect bites, rashes, and minor skin infections is well documented.
• Irritable bowel symptoms: By reducing gut secretion and inflammation, Dragon's Blood may help ease cramping, loose stools, and urgency associated with irritable bowel syndrome, particularly in diarrhea-predominant presentations.

What can Dragon's Blood (Croton lechleri) help prevent?

• Wound infection (topical antimicrobial barrier effect)
• Traveler's diarrhea severity when taken prophylactically

Which foods are rich in Dragon's Blood (Croton lechleri)?

1. Berries (blueberries, blackberries, grapes): Rich in proanthocyanidins — the same class of antioxidants responsible for Dragon's Blood's gut-protective and anti-inflammatory effects.
2. Dark chocolate (70%+ cacao): A concentrated source of proanthocyanidins and flavonoids that support gut lining health and reduce intestinal inflammation.
3. Green tea: Contains catechins and tannins that share antimicrobial and gut-protective properties with Dragon's Blood compounds.
4. Turmeric: Curcumin supports gut lining integrity and reduces intestinal inflammation through pathways complementary to Dragon's Blood.
5. Bone broth: Provides collagen and gelatin that directly support gut lining repair and integrity, complementing Dragon's Blood's wound-healing action internally.

Practical Tips:

Dragon's Blood is a tree resin not found in dietary foods. Eating a diet rich in plant polyphenols, particularly proanthocyanidins from berries, dark chocolate, and green tea, supports the same gut-protective and anti-inflammatory pathways that Dragon's Blood activates.

What are the side effects of Dragon's Blood (Croton lechleri)?

• Mild nausea or stomach upset (oral use)
• Constipation if overused
• Skin irritation or allergic reaction (topical use, rare)
• Not recommended during pregnancy or breastfeeding due to insufficient safety data

Good to know:

Dragon's Blood is considered safe for short-term use by most healthy adults. It has a strong traditional safety record, and pharmaceutical-grade crofelemer showed minimal side effects in clinical trials. Raw resin taken orally in large amounts may cause digestive discomfort.

How much Dragon's Blood (Croton lechleri) should you take?

• Recommended daily: Oral resin: 1–3 mL of liquid resin per day, or 300–500 mg standardized extract in capsule form. Pharmaceutical crofelemer (Mytesi): 125 mg twice daily as prescribed. Topical: apply small amount of raw resin directly to wound 1–3 times daily.
• Best time of day: Oral use: take before meals for digestive support. Topical: apply as needed after cleaning the wound.
• With or without food: Can be taken with or without food; taking with a small meal may reduce the chance of nausea.
• Time to effect: Diarrhea relief: typically within 1–3 days. Wound healing: noticeable improvement within 3–7 days.
• How long to take it: For acute diarrhea: use for 3–5 days as needed. For ongoing gut support: limit continuous oral use to 2–4 weeks and consult a practitioner before extending. Topical use can continue until the wound heals.
