What is Dragon’s Blood?
Dragon’s Blood is a deep red botanical resin harvested from the Amazonian tree Croton lechleri. When applied topically, the liquid resin naturally dries into a lightweight protective film. Traditionally used in rainforest communities, modern formulations explore topical and digestive applications.
How does Dragon’s Blood form a protective barrier?
Dragon’s Blood is a plant latex containing water and naturally occurring botanical compounds, including polyphenols.
When spread over a surface, the liquid distributes these compounds into a thin layer. As water evaporates, the remaining material becomes more concentrated and leaves a film on the skin.
That surface film provides a physical covering between the skin and its surroundings. This film-forming behaviour helps explain the traditional description of Dragon’s Blood as a “liquid bandage.”
What is happening at the molecular level?
Interactions among the resin’s constituents help the drying layer hold together and adhere to the surface.
What compounds are found in Dragon’s Blood?
Compounds identified in the resin of Croton lechleri, the Dragon’s Blood species used in Hello Rainforet products. This is a research-based list.

Naturally Occurring Plant Compounds
Croton lechleri resin naturally contains a complex mixture of plant compounds that have made it the subject of scientific interest for decades. Among these are naturally occurring taspine, proanthocyanidins, and polyphenols, along with many other constituents that together contribute to the resin's unique chemical profile.
The concentration and balance of these compounds can vary depending on several factors, including the age of the tree, growing conditions, harvest timing, and how the resin is processed after collection. Extraction methods, dilution, and formulation can also influence which naturally occurring compounds are present in the finished product.
At Hello Rainforest, we believe preserving the integrity of the resin begins long before it reaches the bottle. By cultivating our Croton lechleri trees, harvesting responsibly, and bottling 100% pure resin without added water, alcohol, or fillers, we strive to maintain the natural composition of the resin as faithfully as possible.
Nature is complex. Rather than focusing on a single compound, we believe the complete resin deserves to be understood and respected as a whole.
Did You Know?
Plant chemistry is naturally dynamic. No two harvests are identical, just as no two vintages of wine or harvests of honey are exactly the same. Responsible cultivation, careful harvesting, and quality testing help support greater consistency while respecting the natural variation that makes botanical ingredients unique.
How is Dragon’s Blood used on skin?
Topical resin formulas are used to create a breathable surface barrier that supports skin integrity. Applications vary depending on species, formulation, and care context.
Typical Application: Apply a small amount to clean skin and gently spread into a thin, even layer
Can Dragon’s Blood be taken internally?
The Science Behind Dragon’s Blood and Digestive Support
Yes, Dragon's Blood is used internally.
Gastro-Ease contains Dragon’s Blood resin from Croton lechleri. Researchers have investigated this botanical’s chemical composition, effects on inflammatory processes, and potential role in gastrointestinal comfort.
A complex botanical resin
Chemical studies have identified proanthocyanidins—a group of plant polyphenols—as major constituents of Croton lechleri resin. The resin also contains compounds such as taspine. Its biological activity cannot be attributed to one compound alone.
What gastrointestinal research has found
In a preclinical study involving rats with experimentally induced stomach ulcers, researchers reported smaller ulcers, reduced inflammatory activity and lower expression of several inflammation-related genes following treatment with sangre de grado, the Amazonian resin preparation studied.
These findings provide a scientific basis for investigating the resin’s traditional gastrointestinal uses.
Antioxidant activity
Laboratory research on Croton lechleri resin has demonstrated free-radical-scavenging activity. Researchers also found that its effects varied with concentration—an important reason to distinguish laboratory findings from the effects of a finished product taken at its recommended dose.
How This Relates to Gastro-Ease
Gastro-Ease’s stated uses are to provide antioxidants and, in herbal medicine, help soothe irritation and/or inflammation of the gastrointestinal tract.
The studies described here investigate botanical materials and experimental preparations, rather than the finished Gastro-Ease formula. They help explain the scientific interest behind its ingredient; they are not clinical trials of Gastro-Ease.
Always use according to the product label.
Dragon’s Blood and Diarrhea: What Does the Science Show?
Why stools become watery
Your intestinal lining controls the movement of salts and water. In secretory diarrhea, intestinal cells release excessive chloride into the bowel. Sodium and water follow, increasing the fluid content of stools.
A mechanism identified in purified Dragon’s Blood extracts
Crofelemer, a purified preparation derived from Croton lechleri, has been shown in laboratory studies to inhibit two chloride channels: CFTR and calcium-activated chloride channels.
Reducing chloride secretion reduces the driving force drawing water into the bowel. This is an antisecretory mechanism—it targets fluid movement rather than primarily slowing intestinal movement.
What research on the resin itself suggests
Researchers have also investigated a sangre de grado resin preparation in isolated animal intestinal tissue. It reduced chloride secretion triggered by capsaicin, a substance that activates certain sensory nerves.
The findings suggest that the resin preparation can influence nerve-driven intestinal secretion under experimental conditions. Whether Gastro-Ease produces the same effect at its recommended dose has not been established.
This research helps explain why Dragon’s Blood has attracted scientific interest for digestive applications.
FAQ
How is Dragon’s Blood harvested?
Our Dragon’s Blood is cultivated from carefully grown seedlings rather than harvested from wild forests. Trees are nurtured under controlled, responsible growing conditions and harvested at their biological prime to ensure optimal resin quality and potency.
This cultivation-first approach protects wild tree populations, prevents overharvesting, and allows for consistent, traceable sourcing. By growing from seedlings and harvesting at the right stage of maturity, we prioritize sustainability, quality control, and long-term ecosystem health.
This is a key point of differentiation: we don’t rely on opportunistic extraction — we practice intentional cultivation.
