Turns out your herbal tea habit might be doing more than just calming your nerves. A 2024 study from Hokkaido University in Japan has uncovered that some traditional Japanese teas might have powerful anti-inflammatory benefits, thanks to certain rare lipids found in them.
The researchers focused on four herbal teas that have been part of Japanese culture for centuries: Japanese mugwort, fish mint, Sasa veitchii, and common horsetail. Using high-tech analysis methods, they dug into the teas’ lipid profiles and found something remarkable—each brew contained its own unique set of ‘bioactive lipids’, including α-linolenic acid, which is already known for its anti-inflammatory properties.

But the real discovery? A group of compounds called SFAHFAs (hydroxy fatty acids), which had never been found in plants before. That breakthrough has scientists now wondering if these teas could be a whole new source of health-supporting compounds, particularly ones that could be great for gut health.
“These herbs are native to Japan and have been widely consumed as tea from ancient times due to their medicinal properties,” said Associate Professor Siddabasave Gowda. “The discovery of these novel SFAHFAs opens new avenues for research.”
The team behind the study now wants to keep the momentum going, aiming to explore over 40 other types of herbal teas to see if they, too, hold similar benefits. “Our initial study paves the way for further exploration of the role of lipids in herbal teas and their broad implications for human health and nutrition,” added Gowda.
But if herbal tea isn’t your thing, don’t worry—coconut water might be another easy way to sneak in some health perks. In a 2024 video, the Cleveland Clinic spotlighted coconut water as a low-calorie, fat-free drink packed with key electrolytes like potassium, sodium, and magnesium. Not only do these minerals help keep you hydrated, but they also support kidney function and may even contribute to healthier skin.
“An adult’s body is about 60% water, which means nearly every fluid and cell in your body contains electrolytes,” the Cleveland Clinic explained. These charged minerals help regulate chemical reactions and maintain fluid balance throughout the body. They also play a big part in energy production and heart function.

That said, balance is everything. While electrolytes are essential, having too many can cause issues, so professionals recommend staying mindful of intake and getting regular health checks if needed.
So, whether you’re sipping a cup of mugwort tea or cracking open a coconut water, your next drink might just be doing more for your body than you realise.
