Looking around the web, the standard dosage for elderberry syrup is two teaspoons daily. Dosage can be increased to 3 or 4 times a day at the sign of a cold. Aim for raw honey to get the maximum health benefits. I have my elderberry syrup on top of my porridge, sometimes as a drink mixed in warm water or just neat straight from the teaspoon. Don't add it to boiling water, as this changes the enzymes in the added honey and reduces its benefits.
