Meadowsweet (Filipendula ulmaria)

What is it? A herb containing salicylates, which turn into anti-inflammatory salicylic acid in the digestive tract.

How does it help? An excellent digestive remedy, it protects and soothes the gut's mucous membranes, reduces acidity and alleviates nausea. It can ease heartburn, acid stomach and gastritis.

How do I use it? Take 2.5-3.5g of the flower, or 4-5g of the plant as a tea or infusion each day.

Other benefits? Salicylic acid acts as an anti-inflammatory against rheumatic pain. It can also be used in facial steaming and bathing to help clear up pimples and boils, while the infusion is a good wash for wounds or inflamed eyes.

What's the evidence? 'This herb is under-researched, but we know it contains high levels of salicylates, which are aspirin-like compounds,' says Dr Ann Walker, Director of The British Herbal Medicine Association. 'Herbal practitioners use it for joint pain but, unlike aspirin, it is not only safe in the stomach but it's actually used to reduce acidity and acid reflux.'
