Belamcanda
Also known as: Belamcanda chinensis (L.) DC., Blackberry lily, Leopard flower, Iris domestica, Belamcanda chinensis
Overview
Belamcanda chinensis, commonly known as blackberry lily or leopard flower, is a perennial herb native to East Asia. It has a long history of use in traditional Chinese medicine (TCM), primarily for addressing respiratory and inflammatory conditions. The rhizome of the plant is the main part utilized for its medicinal properties. Belamcanda contains various bioactive compounds, most notably isoflavones such as irigenin, which are believed to contribute to its therapeutic effects. Modern research has focused on its anti-inflammatory, antioxidant, and neuroprotective properties, with several preclinical studies supporting these activities. While some clinical investigations exist, large-scale randomized controlled trials (RCTs) and meta-analyses specifically dedicated to Belamcanda alone are limited, indicating a moderate level of research maturity. Further studies are needed to fully elucidate its potential benefits and safety profile in humans.
Benefits
Belamcanda chinensis exhibits several potential health benefits, primarily supported by preclinical research. Its anti-inflammatory and antioxidant activities have been demonstrated in vitro and in animal models, largely attributed to irigenin and other isoflavones extracted from the rhizome. These compounds have shown promise in modulating oxidative stress pathways and reducing inflammatory mediators. Additionally, Belamcanda has displayed neuroprotective effects against neurotoxicity induced by toxins like 1-methyl-4-phenylpyridinium (MPP+). Traditionally, it has been used for respiratory ailments such as sore throat and cough, although clinical evidence supporting these uses is limited. While some studies suggest potential immunomodulatory effects, these are not yet well-quantified. Human data are sparse, and quantitative effect sizes are not well-established due to the limited number of clinical trials. The time course of benefits is also not well-defined, with preclinical studies typically assessing acute or subacute interventions.
How it works
Belamcanda chinensis exerts its effects through several key biological pathways. Primarily, it activates the Keap1/Nrf2 antioxidant pathway, enhancing cellular defense against oxidative stress. This activation leads to increased production of antioxidant enzymes, protecting cells from damage caused by free radicals. Additionally, Belamcanda has been shown to inhibit inflammatory mediators such as nitric oxide and prostaglandin E2 in microglial cells, contributing to its anti-inflammatory properties. These actions primarily impact the nervous system, providing neuroprotection, and modulate immune and inflammatory pathways. While the specific pharmacokinetics of irigenin and other constituents are not well-characterized in humans, these mechanisms provide insight into its potential therapeutic effects.
Side effects
The safety profile of Belamcanda chinensis is generally considered acceptable based on traditional use and preclinical studies. However, comprehensive human safety data are lacking, and more research is needed to fully understand its potential adverse effects. Common side effects are not well-documented, and no significant adverse effects have been reported in the available studies. Information on uncommon or rare side effects is insufficient. Drug interactions are currently unknown, and caution is advised due to the potential modulation of oxidative pathways. No formal contraindications have been established. There is a lack of data on the use of Belamcanda in special populations, such as during pregnancy, lactation, or in children. Due to the limited safety data, it is important to exercise caution and consult with a healthcare professional before using Belamcanda, especially in individuals with pre-existing health conditions or those taking other medications.
Dosage
Due to the limited number of clinical trials, there are currently no standardized dosing guidelines for Belamcanda chinensis. Traditional preparations vary, and modern supplements typically standardize based on irigenin content. The optimal dosage, timing, and formulation require further research to determine the most effective and safe approach. It is important to note that without sufficient clinical data, it is difficult to establish appropriate dosage ranges or upper limits for Belamcanda supplementation. Until more research is available, it is advisable to start with low doses and closely monitor for any potential side effects. Consultation with a healthcare professional is recommended before using Belamcanda to determine a safe and appropriate dosage based on individual health status and needs.
FAQs
Is Belamcanda effective for inflammation?
Preclinical evidence supports anti-inflammatory effects, but clinical confirmation is lacking. More human studies are needed to confirm its efficacy in reducing inflammation.
Is it safe for long-term use?
Safety data are insufficient; traditional use suggests tolerability, but clinical studies are needed to assess the safety of long-term Belamcanda use.
How quickly does it work?
The onset of action is currently unknown; animal studies suggest effects in acute models, but human data are needed to determine how quickly it works.
Can it be combined with other supplements?
No known contraindications exist, but interactions have not been thoroughly studied. Exercise caution and consult with a healthcare professional before combining it with other supplements.

- https://pubmed.ncbi.nlm.nih.gov/34446058/ – Wang et al. (2020) investigated the effects of irigenin from Belamcanda rhizome on MPP+-induced neurotoxicity in mouse microglia BV-2 cells and animal models. The study found that irigenin suppressed neurotoxicity by activating the Keap1/Nrf2 pathway, which reduced oxidative stress and inflammatory mediators. This preclinical study provides mechanistic insights into the neuroprotective potential of Belamcanda.
- https://onlinelibrary.wiley.com/doi/abs/10.1002/ptr.6926 – Wang et al. (2020) examined the impact of irigenin, a compound found in Belamcanda chinensis, on neurotoxicity induced by MPP+. The research demonstrated that irigenin activated the Keap1/Nrf2 pathway, leading to a reduction in oxidative stress and inflammatory mediators in mouse microglia cells. This suggests a potential mechanism for Belamcanda's neuroprotective effects.

(2022) conducted a systematic review and network meta-analysis on TCM formulations for COVID-19, including some containing Belamcanda. The review of 18 trials with 2036 participants found that some TCM formulations improved respiratory infection symptoms. However, the specific contribution of Belamcanda was not isolated due to the heterogeneity of interventions and the lack of direct RCTs on Belamcanda alone.
