This article is about Baptisia tinctoria often called Wild indigo. This is not the plant that makes the indigo dye, though that plant (an Indigofera species) is also in the Fabaceae (Pea family). It is one of my favorite plants for respiratory viruses (cold and flus) and accompanying sore throats. The roots are the part used for medicine. It was employed by the Eclectic physicians who used it for a variety of conditions. It is also the source of one of my favorite quotes in Ellingwood’s Eclectic Materia Medica; he suggests one should use it if one has “ stools resembling prune juice or fetid meat washings”. ‘Fetid meat washings’, how is that for a visualization.
It is not a common plant, but I occasionally find it along the borders of woods mainly in Virginia and West Virginia. And while it is not particularly showy, I can usually spot it while driving due to the distinctive green coloration of the leaves.
I use the fresh root tincture. The roots are not that far down in the soil, but they tend to grow in clayey soils and are not that easy to dig and pull out. Also, when you try to pull them out, the outer root bark comes off leaving the middle part of the root in the ground. So it takes a little while to work the whole root out of the soil.
I often mix this plant with Echinacea, Berberis, Ligusticum, Hydrastis and other antimicrobial plants. I use it for colds and flus and secondary bacterial infections. And while killing or inhibiting viruses and bacteria are two entirely different things, I feel that Baptisia and perhaps these other plants do so, likely through different mechanisms and various constituents each of them have.
Dosage-it is a fairly strong medicine and I tend to not use it alone. In a tincture with equal parts of Baptisia, Ligusticum, Eupatorium perfoliatum and Echinacea, for an adult in the throes of a flu, I would give about 2.5 ml (a half a teaspoon, or about 2 full 1 oz droppers), every 2-3 hours the first day. As symptoms abated, I might use a bit less every 4 hours. And as the condition improves lower both quantity and frequency. In these situations you might want to also start mixing in other medicines such as antiinflammatories, decongestants, cough and sore throat remedies, pain relievers and other medicines. For a more detailed list, please see my handout ‘An Herbalist’s View-Approaches to Colds and Flus).
It seems safe for children, just reduce your quantity (not frequency) with littler people.
If you haven’t tried it, this is a plant I would strongly recommend.
As usual, I hope this was helpful. ~7Song
