Our botanists collect wild individual species (including collections of specific plant parts, such as roots or fruit) native to Kansas and the Great Plains from both public and private lands, with permission. Collections also are made from our research garden. About 20 kilos of fresh material is needed to produce about 1 kg dried weight for medicinal testing. More than 300 collections have been tested so far. For a data sample please view our .pdf file of plants collected in 2010 (our heaviest collection year), which includes scientific and common names, plant family, county and state, and plant part collected.
Plant species are chosen for collection based on previous research in ethnobotany (cultural use of plants) and input from our program’s medicinal chemists.
Plant collections are carefully prepared for medicinal testing. Please see our photo gallery of the steps taken to prepare collected plants for testing.
