We are Napo Therapeutics: an independent European pharmaceutical company headquartered in Milan, a start-up led by a team of experienced professionals. Our mission is to improve the quality of life for people affected by rare diseases and conditions with high unmet medical need through innovative solutions.
Our name reflects our history: the Napo River flows through the Amazon rainforest, where the Croton lechleri plant grows—the source of the sap from which we extract a valuable active compound.
We are developing an innovative, first-in-class drug based on its mechanism of action, with the goal of gaining marketing authorization across Europe.
Currently, our focus is on two serious rare diseases: Short Bowel Syndrome (SBS) and Congenital Diarrheal Disorders (CDD), including Microvillus Inclusion Disease (MVID).
Our majority shareholder is Napo Pharmaceuticals, a wholly owned subsidiary of Jaguar Health, headquartered in San Francisco and listed on NASDAQ (JAGX).
Mission & Vision
Our mission is to develop innovative, sustainable, and natural-origin therapeutic solutions to improve the lives of patients affected by rare gastrointestinal diseases.
For over 20 years, we have worked closely with local communities and research institutions in the Peruvian Amazon to develop a sustainable model for cultivating and harvesting Croton lechleri, a tropical plant known for centuries as *Sangre de Drago*—*Dragon’s Blood*—due to its red sap traditionally used by indigenous populations to treat wounds and gastrointestinal ailments.
The harvest of Croton lechleri
Croton lechleri grows naturally in the rainforests of Venezuela, Colombia, Peru, Bolivia, Ecuador, and Brazil, especially along the Napo and Pichis River basins.
From the 1980s onward, areas such as the Pichis valleys—home to the Asháninka, Yánesha, and Cacataibo peoples—began to experience migration and land-use conflicts, including coca leaf cultivation. Governments and NGOs continue to work with communities to promote crop substitution and social development.
In response to these challenges, Jaguar Health and Napo launched a collaboration in the early 2000s with local producers and communities to support the sustainable wild collection of Croton lechleri, aiming to ensure the long-term resilience of this medicinal plant for the benefit of patients, local producers, indigenous groups, and the ecosystem.
We developed a method combining wild collection, reforestation, and low-impact cultivation.
The sap is only extracted from trees specifically planted and sustainably grown. The collection method maximizes resin yield and promotes natural soil regeneration in degraded forest areas.
Where are the trees planted?
Croton lechleri is a natural soil conditioner. Our sap extraction process enhances its ability to improve soil biology.
For every harvested tree, we plant at least two or three more. Since 2000, approximately 800,000 Croton lechleri trees have been planted in seven regions of Peru.
After sap collection, the felled tree is left on-site to return organic material to the ecosystem, while its seeds are used for reforestation. The sap is delivered, registered, tested, filtered, and packaged for transport.
This project would not have been possible without the collaboration, experience, and support of local communities and research institutions in Colombia, Ecuador, and Peru.
