Herbarium: Medicinal Plants as Information

Sambucus canadensis - the American Elderberry and its Medicinal Usages

Through examination of the plants from the UCLA Herbarium, Botanical Garden, and historical materia medica, while they are not the same species, there are meaningful commonalities between all of the plants that help with identification of this genus. They also give insight into the adaptations and characteristics that define the elderberry genus.
Records of Sambucus canadensis in historical materia medica detail its various parts and properties, which lend themselves to identification through distinct characteristics and later explanation of medicinal properties in the different parts of the plant. A specimen of the same genus, Sambucus nigra, was produced in 1887 by Franz Eugen Köhler for Köhler's Medizinal-Pflanzen, Vol. 2. It is a colored plate, which was to help with printing and mass production of this medicinal book. It is depicted showing the components of the plant, including its seeds, berries, leaves, and flowers at different angles and stages of development which allows the viewer to better understand the composition of the plant. Even though this particular materia medica is of a different species, being from the same genus allows us to find key similarities between the species and identify important characteristics. Illustrations such as these would have historically been used to record the usage and identification of medicinal plants.


Historical materia medica is often used to help with the identification of plants, as shown by the UCLA Herbarium specimen of Sambucus canadensis. The specimen was collected near the Chesapeake and Ohio Canal in Montgomery, Maryland by Cora Smith King. The species was determined after its collection by Agnes Smith using the Gray's “Manual” 7th edition, a botany handbook. It was originally misidentified as being in the Valerianaceae “Valerian” family but then was corrected to the Caprifoliaceae “Honeysuckle” family. The key points of collection and preservation of this specimen is to accurately show each part of the plant by pressing it and preserving it as well as including the relevant information in its metadata. With the development of modern database technology, this information can become part of wider collections of knowledge such as CCH2, allowing people all over the world to access this information.


While the materia medica helps with the identification and classification of the specimen, the collection and preservation of it helps with closer examination and annotation as well as future identification in the field. Using information found in materia medica and the herbarium specimen, important features of the plant found in the Botanical Garden are easily identified, such as its serrated leaves and odd-pinnate leaf pattern. Seeing this plant in person, though it is not the exact species, allows one to note key common features as well as contextualization of the plant in its environment, which may connect to some of the adaptations that were able to examine. The culmination of all this information allows for a better identification and understanding of this plant’s adaptations, environment, and it as a whole.


In terms of its medicinal properties, members of the Sambacus genus has historically been used to treat a wide variety of ailments and has noted antioxidant, antiviral, anti-microbial, and anti-inflammatory properties. The majority of literature surrounding plants in the elderberry genus is in regards to the european species, Sambucus nigra, or the European black elderberry which is present in Europe and North America. This plant has been used medicinally and culinarily for hundreds of years, leaving historical records throughout Europe. Flowerheads can be used to make elderflower cordial, or fried in batter to make elderflower fritters, while the berries have been used in wines or brandies. The plant was also historically used in medicines by herbalists, especially for flu symptoms. Although historically the European black elderberry was most favored in medicinal use, other species of this genus share its antiviral properties and can be used as medicine. The inner and root bark can be used as a diuretic, emetic, and laxative. The root bark has been used to promote labor, treat headaches, kidney problems and mucous congestion. The leaves and flowers are used as an antiseptic. Elderberry juice contains high levels of anthocyanins, a class of flavonoids which is known for its antiviral properties. In the modern world, new research and products containing this plant are being developed for medicinal usage.
