Smilax glyciphylla, the sweet sarsaparilla, is a dioecious climber native to eastern Australia.

The sweet flavoured leaves are used medicinally[2] by Indigenous people and non-Indigenous colonists, including as a tea substitute.

[3] It was used medicinally in the earliest days of the colony of Port Jackson for treating scurvy, coughs and chest complaints.

"[4] It was recommended as a tea alternative, tonic and antiscorbutic, and was still being traded at least up until the late 19th century by Sydney herbalists.

The leaves, stems, and flowers contain the glycoside glyciphyllin, which has a bitter-sweet taste and may be the active medicinal component.
