Condurango Extract
Also known as: Gonolobus condurango, Marsdenia condurango, Condurango, Condurango extract
Overview
Condurango extract is derived from the bark of *Gonolobus condurango*, a plant native to South America. It contains bioactive compounds, primarily pregnane glycosides. Traditionally, it has been used in folk medicine for digestive ailments and as a purported anticancer agent. Current research predominantly focuses on its potential antitumor properties, specifically its ability to induce apoptosis (programmed cell death) in various cancer cell lines. While preclinical studies (in vitro and animal models) show promising results regarding its cytotoxic effects on cancer cells, the evidence base for human efficacy is limited. There are very few rigorous clinical trials, and the overall quality of evidence for its clinical use is considered moderate to low. Homeopathic preparations of Condurango also exist, but their clinical efficacy remains inconclusive.
Benefits
Condurango extract has demonstrated primary anticancer activity in preclinical settings. In vitro studies have shown its ability to induce apoptosis in cancer cells, such as HeLa cervical cancer cells, by activating the Fas receptor and causing mitochondrial depolarization, leading to reactive oxygen species (ROS)-dependent cell death. Furthermore, in rat models, an ethanolic extract of Condurango was observed to alleviate BaP-induced lung cancer through caspase-3-dependent apoptosis. Some research also suggests potential epigenetic modulation, specifically the regulation of DNA hypermethylation in lung cancer cells. However, it is crucial to note that there are no high-quality randomized controlled trials (RCTs) in humans that demonstrate the clinical efficacy of Condurango for cancer treatment or any other condition. All reported benefits are based on laboratory and animal studies, and their relevance to human health is yet to be established.
How it works
Condurango extract primarily induces apoptosis in cancer cells through several proposed mechanisms. It is believed to generate reactive oxygen species (ROS), which leads to mitochondrial membrane depolarization and subsequent activation of caspase-3, a key enzyme in the apoptotic pathway. Additionally, it may influence cell cycle regulation via the p21/p53 pathways and contribute to DNA damage response. Proposed epigenetic effects include the modulation of DNA methylation patterns. While some earlier studies suggested histone deacetylase (HDAC) inhibition, more recent research has failed to validate this effect in certain cancer cell lines. The exact bioavailability and pharmacokinetics of Condurango in humans are not well characterized, meaning how it is absorbed, distributed, metabolized, and excreted in the human body is largely unknown.
Side effects
The safety profile of Condurango extract in humans is not well established due to a significant lack of comprehensive clinical data. While preclinical studies suggest selective cytotoxicity towards cancer cells, there are no reports from controlled human trials detailing common or rare side effects. Consequently, potential interactions with other medications or contraindications for specific populations remain uncharacterized. Homeopathic dilutions of Condurango (e.g., 6c, 30c) are highly diluted and generally considered safe due to the minimal amount of active substance present, but their lack of proven efficacy means they should not be relied upon for therapeutic purposes. Without robust human safety data, caution is strongly advised regarding the use of Condurango extract, especially in non-homeopathic forms. Individuals should consult with a healthcare professional before considering its use.
Dosage
There are currently no established dosing guidelines for Condurango extract based on clinical trials in humans. Preclinical studies have utilized various forms, such as ethanolic extracts or homeopathic dilutions, without standardized dosing protocols that can be translated to human use. While traditional uses may involve tinctures or other extracts, the effective and safe human doses for any purported therapeutic purpose are unknown. There are no specified dosage ranges, timing considerations, or different dosages for various conditions. Furthermore, upper limits and safety thresholds for human consumption have not been determined. Due to the lack of clinical data on efficacy and safety, any self-administration of Condurango extract at non-homeopathic concentrations is not recommended.
FAQs
Is Condurango effective for cancer treatment in humans?
No, there is no high-quality clinical evidence supporting its efficacy for cancer treatment in humans. Any observed benefits are currently limited to preclinical laboratory and animal models.
Is Condurango extract safe for human consumption?
The safety of Condurango extract in humans is not well studied. There is a significant lack of comprehensive human safety data, and caution is strongly advised due to uncharacterized side effects and interactions.
How is Condurango typically administered?
Condurango is mostly available as extracts or in highly diluted homeopathic preparations. However, there are no standard clinical protocols for its administration or usage.
How long does it take to see effects from Condurango?
The time frame to observe effects in humans is unknown. In preclinical cell culture studies, pro-apoptotic effects have been observed within hours, but this does not translate to human clinical outcomes.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC4573805/ – This in vitro study investigated the effects of Condurango extract on HeLa cervical cancer cells. It found that the extract induced reactive oxygen species (ROS)-dependent apoptosis by activating the Fas receptor and causing mitochondrial depolarization, suggesting a potential anticancer mechanism in a laboratory setting.
- https://www.frontiersin.org/journals/oncology/articles/10.3389/fonc.2018.00473/full – This review, incorporating in vivo and in vitro data, highlighted that Condurango ethanolic extract induced caspase-3-dependent apoptosis in lung cancer models. It also noted observations of epigenetic modulation, providing a comprehensive overview of preclinical anticancer mechanisms, though it lacked human clinical trial data.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC12079997/ – This experimental cell line study, published in 2025, investigated Condurango's effects on HCC38 breast cancer cells. It specifically aimed to confirm HDAC inhibition but found that Condurango could not consistently induce apoptosis or confirm HDAC inhibition compared to known HDAC inhibitors, suggesting a need for further replication and clarification of its mechanisms.
- https://www.thieme-connect.com/products/ejournals/pdf/10.1055/s-0040-1716369.pdf – This systematic review focused on homeopathic cancer models and found that highly diluted homeopathic preparations of Condurango showed some cytotoxic and pro-apoptotic effects in vitro. However, the review concluded that the clinical relevance of these findings remains unclear due to the lack of robust clinical randomized controlled trials and methodological heterogeneity among studies.
