Baptisia tinctoria is a homeopathic remedy made from the fresh root of wild indigo, a plant of North America. This is a single drug in homeopathy, not a blend. Its Latin name is Baptisia tinctoria, and it is also known as wild indigo.
People reach for it for high fever with a dull, dazed head, aching limbs and a bad taste in the mouth. It is also sold for sore throat and mouth sores. None of these uses is proven.
The root is diluted in steps, again and again, and shaken each time. At 30C there is almost no plant left in the pill. Trials do not show it beats a dummy pill (placebo), and long use in the past is not proof that a remedy works.
The honest answer is that there is no known way this remedy could act in the body. Homeopathy holds that a substance which causes symptoms in a well person can treat those same symptoms in a sick one. It also holds that heavy dilution makes a remedy stronger, not weaker.
Chemistry does not back that up. By 30C the root has been diluted so far that no plant matter is left to act. Any benefit you feel is best explained by rest, time and the placebo effect (feeling better because you expect to).
You will most often see small sugar pellets, milk-sugar tablets, or liquid drops. Common strengths are 6C, 30C and 200C. Some labels use X or D instead, such as 3X.
The mother tincture is a strong alcohol extract of the root, made before any dilution. It is much closer to the raw plant than a 30C pill is.
Some cold and flu products mix herbal wild indigo with echinacea and thuja. Those blends are herbal medicines, not this single homeopathic remedy.
Wild indigo grows in dry woods in eastern North America. Native American groups used the root as a wash for sores and as a strong purge. In the 1800s, Eclectic doctors in the United States gave it for fevers with foul-smelling discharge.
Homeopaths began testing it on healthy people in the 1850s and 1860s. From those notes came its picture of dull fever, a sore body and a dazed mind. It has stayed a named remedy in homeopathic books ever since.
See a doctor the same day if a fever stays above 39C (about 102F), lasts more than three days, or comes back after settling.
Get urgent help if you notice a stiff neck, a rash that does not fade when you press a glass on it, confusion, trouble breathing, chest pain, or a person who is hard to wake.
Also get help if you cannot keep fluids down, pass very little urine, have a badly swollen throat, or feel worse rather than better after two days.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Baptisia tinctoria is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
