Kanchanar Bark Extract
Also known as: Kanchanar Bark Extract, Kanchnar, Rakta Kanchnar, Bauhinia variegata Linn, Bauhinia variegata
Overview
Bauhinia variegata, commonly known as Kanchanar Bark Extract, is derived from a medium-sized tree native to India and parts of Asia. Traditionally, its stem bark has been a staple in Ayurvedic medicine, utilized for a diverse range of conditions including respiratory issues like asthma, various skin diseases, goiter, lymphadenopathy, benign prostatic hyperplasia, and inflammatory disorders. The bark is rich in bioactive phytochemicals such as flavonoids, phenols, tannins, and alkaloids, which are believed to contribute to its therapeutic effects. While preclinical research, including in vitro, in vivo, and in silico studies, has begun to explore its potential, high-quality human clinical trials specifically on the bark extract are limited. Consequently, the current evidence base is primarily preclinical, with human clinical data being sparse, indicating a moderate quality of evidence.
Benefits
Kanchanar Bark Extract exhibits several potential benefits, primarily supported by preclinical research. Anti-inflammatory and antiallergic effects have been observed in animal studies, where aqueous and ethanol extracts significantly reduced milk-induced leukocytosis and eosinophilia in mice, suggesting antieosinophilic activity relevant to allergic inflammation. This effect was dose-dependent and statistically significant (p < 0.05). Furthermore, in vitro studies indicate antioxidant and potential anticancer properties; phytochemical analysis of formulations containing B. variegata revealed flavonoids and phenols with antioxidant activity and cytotoxic effects on cancer cell lines. While promising, these findings are preliminary and require human validation. Modest antiviral activity has also been noted, with aqueous extracts showing approximately 11.5% inhibition of rotavirus infectivity in vitro. Traditional uses for conditions like goiter, lymphadenopathy, and benign prostatic hyperplasia are widely reported in ethnopharmacological literature, but these claims currently lack rigorous clinical trial validation.
How it works
The therapeutic actions of Kanchanar Bark Extract are attributed to its rich phytochemical composition, including flavonoids, phenols, tannins, and alkaloids. These compounds are believed to mediate its observed antioxidant and anti-inflammatory effects. The anti-inflammatory mechanism may involve the modulation of immune cell activity, leading to a reduction in eosinophil and leukocyte counts. In vitro studies suggest that its potential anticancer effects could be linked to the induction of apoptosis and DNA fragmentation by its flavonoid fractions. The modest antiviral activity observed might stem from interference with viral replication processes after the virus enters host cells. However, the exact biological pathways and interactions with human body systems are not yet fully characterized, and data on its absorption and bioavailability remain largely undefined.
Side effects
Comprehensive human safety data and adverse event profiles for Kanchanar Bark Extract from randomized controlled trials are currently unavailable. While traditional Ayurvedic use suggests general tolerability, formal toxicity studies and detailed drug interaction data in humans are lacking. Consequently, there are no reported common or rare side effects from clinical trials due to the insufficient human data. Individuals considering its use should exercise caution, especially those with pre-existing medical conditions or those taking other medications, as potential interactions or adverse effects have not been thoroughly investigated. Without robust clinical safety data, its use should be approached with prudence, and consultation with a healthcare professional is advisable.
Dosage
There are no established or standardized dosing guidelines for Kanchanar Bark Extract derived from human clinical trials. Its traditional use in Ayurvedic medicine often involves the bark in various polyherbal formulations, such as Kanchanara guggulu, where it is combined with other herbs. Preclinical studies have utilized aqueous and ethanol extracts in animal models, but these dosages cannot be directly translated to human equivalent doses. Due to the absence of clinical data, specific recommendations for dosage, timing, or form (e.g., extract concentration, capsule vs. powder) for different purposes or populations cannot be provided. Without defined upper limits or safety thresholds, self-dosing is not recommended. Any use should ideally be under the guidance of a qualified Ayurvedic practitioner or healthcare professional familiar with traditional herbal medicine.
FAQs
Is Kanchanar Bark Extract effective for cancer or thyroid disorders?
Preclinical evidence suggests potential antioxidant and anticancer effects, but no high-quality clinical trials confirm efficacy for cancer or thyroid disorders in humans.
Is Kanchanar Bark Extract safe for human consumption?
Safety in humans is not well studied; caution is advised until more comprehensive clinical data on its safety profile become available.
How should Kanchanar Bark Extract be taken?
There is no standardized dosing. It is typically used in traditional Ayurvedic formulations, often under the guidance of an Ayurvedic practitioner.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC3217693/ – This animal study investigated the anti-inflammatory and antiallergic effects of aqueous and ethanol extracts of Bauhinia variegata stem bark in albino mice. It found that both extracts significantly reduced milk-induced leukocytosis and eosinophilia in a dose-dependent manner, suggesting antieosinophilic activity relevant to allergic inflammation. The study provides preclinical evidence for the traditional use of the bark in inflammatory conditions.
- https://core.ac.uk/download/235663035.pdf – This research, likely an in vitro study, focused on the phytochemical analysis of Kanchanara guggulu, a polyherbal formulation containing Bauhinia variegata. It identified flavonoids and phenols with significant antioxidant activity (via DPPH assay) and demonstrated cytotoxic effects against various cancer cell lines. The findings suggest potential anticancer properties, though these results are from in vitro assays and require further clinical validation.
