Mistletoe is antispasmodic and useful for treating coughing such as in COPD (Chronic Obstructive Pulmonary Disease). Actually, COPD doesn’t describe what’s wrong, such as asthma or bronchitis; it just means you cough a lot. Mistletoe has long been used as a heart tonic because of its calming effect and its ability to lower blood pressure. Mistletoe grows in trees in a symbiotic relationship with the tree; it gets all its food from the tree sap. The really fascinating thing is how it got in the tree in the first place. The berries produced by the mistletoe plant are the favorite of some birds. The bird eats the seed, digests the pulp, and expels the actual seed part. But, the seed comes out very sticky and sticks to the birds behind. He has to wipe his bottom on a tree limb to get rid of the sticky blob and basically “plants” another mistletoe where it might grow.
