Herbalists call this a demulcent effect. That coating can calm irritated tissue and ease the burning and rawness many people feel with reflux or gastritis. - Most of the evidence comes from traditional use, lab studies, and animal research, with limited human trials. In my practice I often recommend marshmallow root for patients with reflux, gastritis, or an irritated gut lining as a supportive tool while we work on what is driving the irritation. - Cold infusion (steeping the dried root in room temperature water for several hours) pulls out the most mucilage. Capsules and powder are also options. Research supports a range of doses, which is worth discussing with your practitioner, since the right amount depends on your symptoms and goals. - Marshmallow root is generally well tolerated. Because its coating can slow absorption of medications and other supplements, I have patients space it at least two hours away from them. People with diabetes should monitor blood sugar, and anyone pregnant or breastfeeding should check with their practitioner first. Acid reflux (or "heartburn") is a common digestive problem that affects millions of people worldwide. It occurs when the lid of the stomach called the lower esophageal sphincter (or LES) becomes lax and opens when eating, causing irritation from stomach acid in the esophagus. ## What are the symptoms of Acid Reflux? Acid reflux affects the stomach and esophagus and very often feels like a burning sensation in your mid-chest near the sternum (this is why it's often referred to as “heartburn”). Given the location in the chest and severe, acute pain and chest tightness it can cause, heartburn is one of the most common reasons people visit the ER. Others might describe it as a feeling not dissimilar to indigestion - sharp pains, gurgling and burping, sour taste in the mouth and general upper-abdominal discomfort. Certain foods, large meals, or eating too close to bedtime (lying down can cause the reflux) can trigger acid reflux. And while it can be uncomfortable and unpleasant, occasional episodes are not a disease. ### When does acid reflux become chronic (GERD)? If one starts experiencing acid reflux regularly -- two or more times a week -- or all the time -- this should be a cause for concern and you should consult your physician. It might mean that you have gastroesophageal reflux disease (GERD) is a more serious form of acid reflux. Longstanding GERD can lead to tissue changes at the gastroesophageal junction called Barrett's esophagus. That's why treating only the painful and unpleasant symptoms of acid reflux is not enough. It can be a symptom of other underlying conditions and can also put you at risk of esophageal damage, increased chances of developing ulcers, narrowing of the esophagus, or even cancer, if left untreated. ## What is marshmallow (Althea off.)? First let's discuss what marshmallow root is not -- it is NOT those big (or little) sugary pellets that we put on sweet potatoes at Thanksgiving or roast on a stick over a campfire (and put in S'mores!) Those are just pure sugar treats. But there is a link. Marshmallow is "gooey" - or mucilaginous - and this is one reason why it has traditionally been used to help soothe stomachs for centuries. The roots and leaves of Marshmallow plant contains a unique gelatinous substance that forms a protective layer on the lining of the digestive tract. The flowering marshmallow plant is widely found throughout Europe, Asia and North America, so extracts tend to be widely available. The extract is commonly available at health food stores or drug stores and sold in the form of capsules, powders or herbal teas. Capsules are the most common and easiest method to consume marshmallow. That said, I feel capsules can irritate sensitive guts and I like a more the direct approach of tea or powder. Powder can be added to juice or sprinkled on food. Wither way, when you take these, they soothe the gut lining going down - no waiting for a capsule to open up to work. Taken daily, marshmallow preparations can become gut protective and irritation preventative. ## Health benefits of Marshmallow (Althea off.)
