Cat’s claw, a plant native to Costa Rica, has long been utilized in traditional medicine for its reputed anti-inflammatory, antioxidant properties and immune-boosting abilities. This plant is often associated with combating viruses, bacteria, and chronic diseases. However, the scientific understanding of this powerful plant has recently undergone significant advancements.
The Pioneering Role of Dr. Mirtha Navarro Hoyos
Dr. Mirtha Navarro Hoyos, a chemist by training, returned to her native Costa Rica to lead the Bioactivity Group for Sustainable Development at the University of Costa Rica (UCR). Her team inaugurated a research laboratory dedicated to investigating the health properties of traditional foods and plants, a crucial step in understanding the scientific basis of natural medicine.
Unveiling the Potential of Cat’s Claw
While the alkaloids in cat’s claw have been previously studied, Dr. Hoyos and her team decided to shift their focus to the plant’s polyphenols, substances that are known for their health benefits. This decision was driven by the plant’s wide distribution in various Costa Rican climates and its popularity in traditional medicine.
A Surprising Discovery: Polyphenols in Leaves
A significant breakthrough came when the team discovered that the polyphenol content in cat’s claw leaves was higher than in other parts of the plant. This information is particularly valuable as it means the medicinal components can be harvested from the leaves without uprooting the entire plant, a practice that traditionally involved taking from the bark, roots, and stems.
Innovative Cultivation of Cat’s Claw
Growing cat’s claw has always been challenging due to its climbing nature and thorns. However, researchers and cultivators have developed a solution to grow the plant more like a bush, making the harvest of the polyphenol-rich leaves easier and more efficient.
From Dietary Supplement to Potential Medical Treatment
Currently, cat’s claw is available in capsule form and approved as a dietary supplement. With ongoing trials and research, there is hope that it will eventually receive approval for medicinal uses. Laboratory tests have already demonstrated promising results, with evidence suggesting that cat’s claw can kill cancer cells.
