Clitoria Ternatea: Benefits, Science & the Blue Flower Trend

A flowering plant, Clitoria ternatea, is gaining attention not just for its striking color-changing properties in cocktails, but too for potential cognitive and circulatory benefits, according to Gilles Rio, a practitioner of traditional Chinese medicine. While largely absent from classical Chinese medicine texts, the plant has a long history of use in Ayurvedic, Thai, and Indonesian medicine, and is now attracting scientific interest for its antioxidant and anti-inflammatory compounds.

A Plant with a Colorful History

Clitoria ternatea, often called butterfly pea, is a climbing plant with vibrant green leaves and flowers that range in color from deep blue to mauve, pink, or white. Its unusual name comes from the shape of its flower, which resembles a human female reproductive organ. The plant’s recent surge in popularity is largely due to social media trends showcasing its ability to dramatically shift color from blue to purple when mixed with acidic liquids like lemon juice – a popular effect in beverages. But beyond its aesthetic appeal, the plant boasts a surprisingly extensive geographical spread. As Rio explains, it originated on the island of Ternate and spread through the Antilles, then to Africa, Australia, and the Americas.

Traditional Uses and Emerging Science

For centuries, traditional medicine systems have recognized the plant’s therapeutic potential. Rio notes that in India, it’s known as “Aparajita,” or “the invincible one,” and is used to support cognitive function, intellect, and memory. Thai practitioners have traditionally employed it to stimulate vision, improve circulation, and calm the mind. These traditional uses are now being investigated by modern science.

Research is focusing on the plant’s rich chemical composition. Studies have identified potent antioxidants capable of neutralizing free radicals, as well as flavonoids and triterpenes that may reduce inflammation. Animal studies suggest a possible impact on memory and neuronal plasticity – the brain’s ability to reorganize itself by forming new neural connections throughout life. This research, while preliminary, is fueling interest in Clitoria ternatea as a potential nootropic, or “smart drug,” a substance that may enhance cognitive function.

Cyclotides: A Unique Promise

Beyond its antioxidant and anti-inflammatory properties, Clitoria ternatea produces cyclotides – unique peptides that are remarkably stable. Rio highlights the potential of these cyclotides, noting their interest in antiviral and anti-cancer research. Frontiers in Pharmacology published a review in 2023 detailing the potential of cyclotides as therapeutic agents.

Navigating Scientific Caution and Regulatory Scrutiny

Despite the promising research, scientists emphasize the need for caution. No official medical indications currently exist for Clitoria ternatea, and more rigorous clinical trials are needed to confirm its benefits and assess potential side effects in humans. This caution is reflected in the regulatory landscape. While widely used in some regions, Europe remains relatively cautious, and France has even banned the plant due to concerns about its potential for misuse and lack of safety data. This ban, however, appears to be related to the plant’s use in food supplements rather than traditional medicinal applications.

Aesthetic Appeal and Culinary Expansion

The plant’s vibrant color and relatively mild flavor have also led to its increasing use in culinary applications, particularly in beverages and desserts. Its ability to change color with pH levels makes it a popular ingredient for creating visually striking cocktails and other drinks. This culinary trend is contributing to its wider availability and recognition, but also raises questions about quality control and potential adulteration.

What’s Next for Clitoria ternatea?

The future of Clitoria ternatea hinges on continued scientific investigation. Further research is needed to fully elucidate its mechanisms of action, identify optimal dosages, and assess its safety profile. Pre-clinical studies showing improvements in memory and neurotransmitter availability will likely prompt more rigorous human trials. The plant’s potential as a nootropic will likely be a key area of focus, alongside investigations into its antiviral and anti-cancer properties. As research progresses, it’s likely that regulatory frameworks will evolve to reflect the growing body of evidence, potentially leading to wider acceptance and integration of Clitoria ternatea into both traditional and conventional medicine. For now, the plant remains a fascinating example of how traditional knowledge and modern science can converge to unlock the potential of the natural world.

Further investigation into the plant’s cyclotides and their potential applications in antiviral and anti-cancer therapies is also anticipated. The stability of these peptides makes them particularly attractive candidates for drug development, and ongoing research may reveal new and innovative ways to harness their therapeutic power.
