The leaves of this plant smell just like Vicks vaporub and can be used for the same purpose. You can steep them in boiling water and inhale the steam to clear nasal passages, or make them into a rub by mixing them with vaseline. The plants are bushy, with fleshy green leaves and grow easily in sun or semi shade. They need well drained soil and not much in the way of fertiliser. They are frost tender, but can be grown in pots indoors in winter. Do not over water.
