Why We Put Rooibos in Our Digestion Mix
Rooibos (Aspalathus linearis) is packed with some seriously clever compounds. We're talking quercetin, luteolin, orientin, and vitexin – these aren't just tongue-twisters, they're powerful antispasmodic compounds that help relax the digestive system and ease cramping.
Rooibos contains aspalathin (which you literally can't find anywhere else in nature – how cool is that?!) along with nothofagin and quercetin. Recent research published in the Journal of Ethnopharmacology (2023) demonstrated that rooibos extracts can strengthen the gut lining, reduce inflammation, and improve the integrity of tight junction proteins – basically, it helps keep your horse's gut barrier strong and healthy.
Just like in humans, horses deal with digestive upset, stress-related gut issues, and inflammation. Research has shown that rooibos:
Reduces gut inflammation – A 2024 study found that rooibos strengthens the gut lining and decreases inflammatory responses in intestinal cells
Acts as an antispasmodic – helping to ease those uncomfortable belly cramps
Supports beneficial gut bacteria – the polyphenols in rooibos encourage good bacteria while keeping the troublemakers in check
Unlike some herbs that can be harsh on the system, rooibos is incredibly gentle. It's low in tannins (those compounds that can interfere with nutrient absorption) and has been used for generations – even for human babies!
While we can't claim rooibos is a miracle cure (because science doesn't work that way!), the research is genuinely impressive. Multiple studies have shown its anti-inflammatory, antioxidant, and gut-protective properties – and that's exactly why it's earned its spot in our Digestion Mix.
