L., an aromatic shrub of the Asteraceae family endemic to the western and southern coastal region of South Africa. The plant was described in this journal by Laidler<sup>1&nbsp;</sup>in 1928 as ‘<em>D/nhora&nbsp;</em>buchu’, and is one of the important types of buchu used by the Nama people. We report the traditional medicinal uses among San and Nama people, based on our interviews with rural participants. These include the treatment of colds, influenza, chest ailments and tuberculosis, as well as convulsions, haemorrhoids and inflammation of the neck. The major and minor chemical compounds of the essential oil that is produced by the plant are identified, together with the site of accumulation of this volatile oil within the leaf. We also investigated the plant’s antimicrobial activity against a selection of a yeast and two Gram-negative and one Gram-positive bacteria, all of which are associated with respiratory infections.&nbsp;<em>P. camphorata&nbsp;</em>is scientifically poorly known but is an important San and Nama traditional remedy. Our study not only prevents the potential loss of historically important indigenous knowledge, but also provides the first scientific evidence to validate the traditional use of ǀ<em>nhora&nbsp;</em>against upper and lower respiratory tract infections, including tuberculosis. This detailed study has wider application in demonstrating the fragility of the oral–traditional knowledge of a scientifically neglected indigenous group. It also highlights the scientific and practical importance of preserving traditional plant-use knowledge within a botanically diverse region.</p></div></div></div><div class="field field-name-field-significance field-type-text-with-summary field-label-above"><div class="field-label"><strong>Significance:&nbsp;</strong></div><div class="field-items"><div class="field-item even"><ul><li>Reveals the botanical identity of ǀnhora, an important Nama medicinal plant.</li><li>Presents scientific evidence to validate the traditional uses.</li><li>Contributes to the cultural heritage of a scientifically neglected indigenous group.</li><li>Demonstrates the fragility of oral–traditional knowledge.</li></ul></div></div></div> ER -
