📚 What Science Says About Digestive Herbs for Dogs
🌿 Marshmallow Root, Slippery Elm & Fennel aren't just folk remedies—they’ve been studied for their ability to soothe, protect, and rebalance the digestive tract.
🧪 Marshmallow Root (Althaea officinalis):
Rich in mucilage, this root forms a slippery gel that coats the gut lining. Research shows it may reduce inflammation and irritation in both upper and lower GI tracts—making it a go-to for dogs with acid reflux, ulcers, or post-antibiotic gut sensitivity.
🌿 Slippery Elm (Ulmus rubra):
One of the most trusted herbal GI supports in veterinary herbalism. It acts as a demulcent, binding to irritated tissues and offering protection while promoting healing. It’s gentle enough for puppies and senior dogs, and may even help firm up stool in cases of diarrhea or IBS-like symptoms.
🌱 Fennel (Foeniculum vulgare):
Traditionally used for gas, bloating, and cramping, fennel is rich in volatile oils like anethole that calm the digestive muscles and reduce spasms. It also has mild antimicrobial properties and supports digestion in dogs with sluggish or fermentative guts.
🔎 These herbs are especially helpful for:
• Acid reflux
• Leaky gut
• Post-antibiotic recovery
• Gas & bloating
• Food transitions
• Chronic loose stool or colitis
👉 Not all digestive herbs are created equal—and knowing when and how to use them is key.
