Baptisia tinctoria, also known as horsefly weed, is a plant with light-colored flowers and seed pods. It generally grows in warm regions of North America. The plant’s name is a combination of each of the Latin and Greek words for “dye.” The extract from the flowers and seed pods of baptisia tinctoria were historically used as a garment dye because they would change to a dark blue color when exposed to air. The extract's most common modern use is as an herbal medicine.
The flowers and seed pods of the plant can both be used for medicinal purposes. For use as a tea, the flowers can be dried out and boiled with water. The seed pods can also be steamed to release their natural oils, then combined with alcohol for a mixture known as a tincture. Tinctures can be diluted in water and drunk. The oil from the seed pods can also be added into capsules or mixed with creams for topical application.
One of the possible uses for baptisia tinctoria is as a laxative, a substance that helps the body produce bowel movements. A person may need to use the medicine as a laxative to help treat constipation, a condition in which solid waste becomes backed up in the digestive system and makes regular bowel movements difficult or painful. Taking the herbal capsules orally may help loosen any backed up waste in the intestines so a person can have regular bowel movements. The herb can also work as an emetic, meaning it promotes vomiting. This use can help treat nausea or rid the body of toxins.
Tea made from baptisia tinctoria may be promoted by herbalists as a treatment for respiratory infections. It may be consumed to help soothe sore throats or chest colds. The tea may also be used as treatment for respiratory inflammation pain due to tonsillitis or laryngitis.
Baptisia tinctoria oil may also be implemented as a possible herbal treatment for various aches. It can be mixed with warm water, then used to soak a cloth known as a poultice. The poultice can be pressed against the outside of the jaw for toothaches or applied to other painful areas of the body, such as sprained ankles. The oil mixture can also simply be used as an antiseptic wash for cleaning cuts and scrapes, as herbalists believe it has antibacterial properties.
Some people may experience side effects if they are allergic to the herb. Signs of an allergic reaction generally include itching, vomiting, or diarrhea after applying or consuming. Pregnant or breastfeeding women are typically not advised to use the herb because it is not known how it affects infants or children.
