"Meadowsweet herb has been traditionally used to support a healthy immune system and treat symptoms caused by colds, bronchitis, upset stomach, heartburn, and certain infections. It has been shown to possess the ability to fight oxidative stress, pain, and inflammation due to its high concentration of compounds like tannins, flavonoids, glycosides, essential oils, and salicylates. Some people find that taking meadowsweet extract or tea can help decrease an upset stomach, nausea, heartburn, diarrhea, stomach bloating, and symptoms caused by peptic ulcers. It's speculated that it helps soothe the lining of the stomach and gastrointestinal tract and has antimicrobial effects that can support gut health. However, there hasn't been a lot of research into the herb's safety or effectiveness, so it's best to talk with your doctor if you're planning to use it medicinally and enjoy it in moderation if you're sipping on it as a tea."
