Berberine is usually found in the roots, rhizomes, stems, and bark. Due to berberine's strong yellow color, Berberis species were used to dye wool, leather, and wood. Wool is still dyed with berberine today in northern India. Under ultraviolet light, berberine shows a strong yellow fluorescence, so it is used in histology for staining heparin in mast cells.

Codeine is an opiate used to treat pain, as a cough medicine, and for diarrhea. It is typically used to treat mild to moderate degrees of pain. Greater benefit may occur when combined with paracetamol (acetaminophen) or a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Evidence does not support its use for acute cough suppression in children or adults. In Europe it is not recommended as a cough medicine in those under twelve years of age. It is generally taken by mouth. It typically starts working after half an hour with maximum effect at two hours. The total duration of its effects last for about four to six hours. Common side effects include vomiting, constipation, itchiness, lightheadedness, and drowsiness. Serious side effects may include breathing difficulties and addiction. It is unclear if its use in pregnancy is safe. Care should be used during breastfeeding as it may result in opiate toxicity in the baby. Its use as of 2016 is not recommended in children. Codeine works following being broken down by the liver into morphine. How quickly this occurs depends on a person's genetics. Codeine was discovered in 1832 by Pierre Jean Robiquet. In 2013 about 361,000 kilograms of codeine were produced while 249,000 kilograms were used. This makes it the most commonly taken opiate. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world is between 0.04 and 0.29 USD per dose as of 2014. In the United States it costs about one dollar a dose. Codeine occurs naturally and makes up about 2% of opium.

Vincristine, also known as leurocristine and marketed under the brandname Oncovin among others, is a chemotherapy medication used to treat a number of types of cancer. This includes acute lymphocytic leukemia, acute myeloid leukemia, Hodgkin's disease, neuroblastoma, and small cell lung cancer among others. It is given intravenously. Most people experience some side effects from vincristine treatment. Commonly it causes a change in sensation, hair loss, constipation, difficulty walking, and headaches. Serious side effects may include neuropathic pain, lung damage, or low blood white cells. It will likely cause harm to the baby if given during pregnancy. It works by stopping cells from dividing properly. Vincristine was first isolated in 1961. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world is between 1.80 and 42.60 USD per dose. It is a vinca alkaloid that can be obtained from the Madagascar periwinkle Catharanthus roseus.
