''Pseudobaccatae'' (=sect. '' Ephedra''), "tribe" ''Scandentes''. This being due to the similarity in stem and leaf structure and organization. In 1996 Robert A. Price classified ''E. altissima'' in section ''Ephedra'' without recognizing a tribe.Price, R. A. (1996). Systematics of the Gnetales: A review of morphological and molecular evidence. ''International Journal of Plant Sciences'', 157(6): S40-S49.

Threat

As a result of the plant having such a widespread location, there are no specific major threats. This plant was last assessed by IUCN on August 13, 2010, with a least concerned rating. Due to the non-concerned attitude toward the endangerment of the species, no seeds have been collected as an ex situ conservation measure. It is not known to occur in any protected areas.

Medicinal uses

The members of this genus have alkaloid ephedrine which are integral in the treatment of asthma and other related respiratory issues. By using the entire plant and not just the stem it has been observed, as compared to isolated ephedrine, to have few side effects. This is used to treat symptoms not cure respiratory issues. Young plants have the best potency if ingested raw while older plants are best to be dried and used in a tea.
