Where is the specific species Pelargonium sidoides, known for respiratory applications, geographically native?

Answer

South Africa

Pelargonium sidoides, the specific plant species whose root extract is utilized commercially for alleviating symptoms of colds and respiratory tract infections, originates from South Africa. This geographic origin is significant as it distinguishes it from other members of the Pelargonium genus, such as the common garden geraniums, which do not share the traditional or tested medicinal applications for cough and bronchitis relief. Identifying the correct native species ensures that the correct botanical source is used when preparing the standardized extracts required for clinical efficacy.
