Track Leptandra virginica with reminders and record whether it helped, in the app.
Leptandra virginica is a single homeopathic remedy. It is made from the root of Culver's root, a tall plant from North America. Its Latin name is Veronicastrum virginicum.
Homeopaths give it for liver and gut trouble. Typical uses are watery yellow stools, a dull ache under the right ribs, and a thick coated tongue.
The root is diluted again and again to make the remedy. At 30C almost none of the plant is left, and trials do not show it beats a dummy pill (placebo). Long use in a tradition is not proof that a thing works.
Homeopathy rests on a rule called "like cures like". A big dose of fresh Culver's root brings on vomiting and watery stools. So homeopaths give the diluted root for those same gut signs.
There is no known way this could work in the body. Each step of the dilution makes the plant more scarce. By 30C, no plant matter is left to act on you.
Any change you notice may come from time, rest, care and belief. That is called the placebo effect.
You will most often see small sugar pellets at 6C or 30C. Liquid drops in alcohol are also sold.
Other forms are the mother tincture (marked with the sign Ø) and low strengths such as 1X or 3X. These still hold real plant matter and can loosen the bowels.
Dried root tea belongs to herb use, not homeopathy. The fresh, undried root is not used at all, because it is poisonous.
Culver's root grows wild in eastern North America. Native American healers used the dried root to move the bowels and to treat fevers.
In the 1800s, Eclectic doctors in the United States gave it for liver and bile problems. American homeopaths soon added it to their materia medica, which is their list of remedies.
It has stayed a small, second-line remedy ever since.
See a doctor if your skin or the whites of your eyes turn yellow, or if your stools turn pale, black or bloody. Book a visit if pain under your right ribs lasts more than a day or two.
Get help the same day if watery stools last more than two days, or if you feel faint, very thirsty or pass little urine. Children and older adults lose water fast.
Go to hospital if someone has swallowed raw Culver's root and is vomiting hard, passing blood, or feels weak and dizzy.
