Psyllium (Plantago ovata) vs Slippery Elm (Ulmus rubra)

Psyllium (Plantago ovata)

Slippery Elm (Ulmus rubra)

About

Psyllium, also known as flea seed due to its small brown appearance, is produced by several Plantago species. It has been used as a safe and effective laxative for thousands of years across Europe, North Africa, and Asia. The seeds and husks have a bland taste and develop a jellylike consistency when moistened due to their high mucilage content. The plants are extensively cultivated, especially in India, and propagated from seed in spring. Seeds are harvested when ripe in late summer and early autumn.

Slippery elm (Ulmus rubra) is a large tree native to the eastern U.S. and Canada. The medicinal part is the inner bark, prized for its high mucilage content. When soaked in water, it turns “slippery,” coating and soothing inflamed tissues in the mouth, throat, stomach, and intestines.

Safety & precautions

Do not exceed the stated dose. Always take with plenty of water. Psyllium is a mild laxative suitable for children, elderly, and during pregnancy, but should be avoided in cases of bowel obstruction or perforations. It can cause constipation when a person is dehydrated. Ensure adequate hydration when using.

Sustainability: Slippery elm is at risk from overharvesting; marshmallow root is a more sustainable alternative. General Safety: A mild, very safe demulcent. Rarely causes any side effects.
