TLDR

The red sap of an Amazonian tree contains many plant substances and may help with wounds, inflammation, diarrhea, and other health problems. Most benefits still need stronger testing before they can be relied on as treatments.

Summary

1 Study Aim

The authors aimed to bring together research on the phytochemistry (the chemical substances in a plant) and pharmacology (how substances affect the body) of Croton lechleri, an Amazonian tree used in traditional medicine. They sought to clarify what it contains and what recent studies suggest about its health effects. They wanted to explain what is known about the tree and its medicinal sap.

2 Study Design

The authors searched Scopus and Google Scholar using terms related to Croton lechleri, its chemicals, and its effects. They selected 33 relevant articles, excluding duplicates and papers that only cited related research. They included pharmacology studies published from 2003 onward, with no starting date specified for chemical studies. The review draws on laboratory experiments, animal research, and human studies; it did not conduct a new experiment or treatment trial. The authors reviewed earlier research rather than testing the sap themselves.

3 Findings

The review identifies proanthocyanidins (plant compounds) as the main resin chemicals, reaching up to 90% of dried resin. It also reports alkaloids (nitrogen-containing plant compounds), diterpenoids (plant compounds), sterols, saponins, and phenolics. Studies describe possible wound-healing, anti-inflammatory, antitumor, antimicrobial, antiviral, and antidiarrheal effects. In one patient trial, a 15% extract cream healed 95.73% of the wound area by day 20, compared with 78.10% with placebo. The authors caution that further clinical trials and chemical standardization (consistent measurement of ingredients) are needed before the full therapeutic value is clear. The sap shows promise, but more careful testing is needed before its benefits are certain.

Abstract

Abstract Croton lechleri, commonly known as “Sangre de Drago”, is a widely utilized ethnomedicinal resource in the Amazon region, known for its diverse bioactive properties. These include wound-healing activity, anti-inflammatory effects, antitumor activity, and other therapeutic benefits. Despite its extensive traditional use, a comprehensive review of the scientific studies conducted over the past two decades is lacking, which hinders a thorough understanding of the chemical and pharmacological characteristics of this species. Hence, this review is essential to inform researchers and readers about the current state of knowledge in this field. A systematic search was conducted using databases such as Scopus and Google Scholar, yielding 33 relevant articles focusing on the phytochemistry and recent pharmacological investigations of C. lechleri. These studies identify proanthocyanidins as the predominant phytochemical group in terms of relative quantity. Additionally, other significant phytochemical groups include alkaloids, diterpenoids, phytosteroids, saponins, phenolics, and polyphenolics. The pharmacological studies reviewed highlight several potential therapeutic effects of C. lechleri, particularly those associated with its resin. These effects include wound-healing, antitumor, anti-inflammatory, and gastrointestinal benefits, among others. The findings underscore the remarkable medicinal importance of this species, supporting its continued investigation and potential therapeutic applications.
