The central leaflet can be a coiled tendril. The flowers are reddish-orange. They are tube shaped and 9 cm long. They are in clusters or 15-20 at the tips of the branches. The flower clusters often hang down. The fruit are slender dry capsules about 25 cm long.

Medicinal Uses

The sap extracted from the stem is used to treat coughs. The plant is said to be tonic and antidiuretic. It is used as a general tonic and also for the treatment of conditions such as diarrhoea, dysentery, leucoderma and vitiligo, as well as common diseases of the respiratory tract, such as bronchitis, flu, and cold. The plant contais various medicinally active compounds, including terpenoids, alkaloids, tannins, steroids, and saponins. Plant extracts have shown significant antioxidant activity due to the flavonoids and b-carotene, and the plant is of potential use as a natural antioxidant and scavenger of free radicals.. Studies support the usefulness of the plant in traditional therapies for treating disorders like flu and colds, that induce sickness behaviors. An extract of the plant has shown potent wound healing capacity as shown by wound contraction and increased tensile strength of the skin.

Other Uses

Capable of covering everything that can offer a good support, the plant can quickly produce an effective screen. Heavy or frequent pruning is needed to restrain it to trellises or arbors, but the brilliant flower display makes this extra work worth the effort. It is ideal for covering fences but will often produce most of the flowers and foliage at the top of the fence. Regularly heading back several of the stems can help develop some of the flowers and foliage on the lower and middle portions of the fence.
