Quassia Inner Wood Extract
Also known as: Bitterwood, Quassia, *Quassia amara*
Overview
*Quassia amara* is a shrub found in Central Mexico and Southern tropical America, known for its bitter compounds, particularly quassinoids. Traditionally, it has been utilized for its medicinal properties, treating conditions such as malaria, hepatic disorders, and gastrointestinal issues, while also serving as an insect repellent. The extract contains various bioactive compounds, including quassinoids, indole alkaloids, and β-carbolines, which contribute to its pharmacological properties. Despite a moderate level of research maturity, most studies are preclinical, with a marked scarcity of clinical trials to validate its effects in humans.
Benefits
Research suggests that *Quassia amara* exhibits several potential health benefits, primarily its anti-diabetic, anti-inflammatory, anti-malarial, and anti-leishmanial activities, established through various preclinical studies. Population-specific benefits may particularly support individuals with type 2 diabetes and certain infections. However, clinical evidence remains sparse, and the effect sizes of these benefits are not well-documented. The timing and consistency of these benefits require further exploration in clinical settings.
How it works
The primary biological activity of *Quassia amara* is attributed to quassinoids, which potentially interact with inflammatory pathways and influence glucose metabolism. These compounds may impact various body systems, including the digestive and endocrine systems. While specific molecular targets are still not well-defined, the broad pharmacological activities of quassinoids suggest a complex interaction with multiple biological pathways. Data on absorption and bioavailability in humans remain limited.
Side effects
*Quassia amara* is generally regarded as safe when used as intended, although potential anti-fertility effects and impacts on male reproductive health have emerged in animal studies. Commonly reported side effects are not well-documented due to limited clinical trials, but there are indications of possible effects on sperm count and motility. Individuals concerned about fertility should approach this supplement cautiously, as should pregnant or breastfeeding women, and it is advisable for these populations to consult healthcare providers before use. Potential drug interactions may occur with medications affecting glucose metabolism or fertility.
Dosage
The optimal dosage of *Quassia amara* has not been conclusively established, and clinical trials are required to identify effective ranges. Recommendations suggest starting with the lowest effective dose, but caution is advised due to undefined maximum limits. The supplement is available in various forms, such as wood shavings or powder, but specific absorption factors and timing for administration are not well-documented. Safety thresholds are not clearly defined, necessitating a consultative approach regarding individual circumstances.
