This non-native wireweed species is common across most of Florida. This particular species has unusually soft and velvety leaves, hence one of the common names, Flannel Leaf. Even the calyces are hairy. Take the time to appreciate the very pretty yellow flowers which often have orange centers. THE FDA OUTLAWED THIS HERB IN 2004 DUE TO ITS EPHEDRINE CONTENT. That said, herbalists still use it to treat coughs, bronchial issues, asthma, wheezing, nasal congestion, etc. Before it was outlawed, I harvested the leaves and dried them to make a stimulating tea that I would rank as one of my favorites. There is a background flavor that I adore, sort of cocoa-like. I feel that it should not have been banned. Plant medicines, left to the people, become an integral part of being human, what ALL of our ancestors ALL knew intimately. Herbalists should be active in every community. Follow your own path. I do agree that certain people should avoid taking this tea as it contains the alkaloids ephedrine and pseudoephedrine which are contraindicated for pregnant women, those with heart issues, pacemakers, people in a weakened condition, nursing mothers, and a whole bunch of others. It is known as Bala in Sanskrit, in its native India, and this is how I refer to the plant. The seeds and roots, and to a lesser degree the leaves, have long been used medicinally in Ayurvedic medicine. Externally, this herb has been made into healing salves and massage oils to treat muscle cramps, wounds, nerve pain, numbness, etc. Narayana Taila, aka Bala Oil, is the famous Ayurvedic oil made from the roots of Bala. I would love to see some Florida herbalists make such topical applications. In the fields, butterflies like to nectar at the pretty flowers. I often notice that Zebra Swallowtails are especially fond of the nectar.
