Edible Uses                                         
Edible Parts: Leaves;  Root.
Edible Uses:

Root - cooked. We were supplied this plant by a friend who said that the root is edible. We have not seen any reports on its edibility. The raw root is crisp and pleasant when first put in the mouth, but soon degenerates into a mucilaginous mass described by some people as 'like eating catarrh' and in rather less flattering terms by others![K]. When well baked, the root loses this quality and is quite pleasant to eat[K]. Leaves cooked. Used as a spinach[264].
Medicinal Uses


Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Antiinflammatory;  Hepatic.

The plant has been shown to have anti-inflammatory, anti-ulcer, and liver-protective effects[270].
Other Uses
None known
Cultivation details                                         
Requires a well-drained humus-rich soil and a position in full sun or good indirect light[200]. Established plants are drought tolerant[200]. This plant seldom, if ever, produces seeds[266]. We have very little information on this plant. The top growth is almost certainly not frost-hardy, though plants have continued growing in a polyhouse when other sensitive plants have died back as a result of frost damage[K]. The tubers have also survived outdoors in a sunny sheltered position for three winters outdoors (as of May 2004), the plant coming back into growth in late spring[K]. )The roots are likely to be hardier and, especially if well mulched, should survive most winters outdoors in the milder areas of the country. They are unlikely to survive sharp or persistent frosts. It should be possible to harvest the roots in the autumn after the top growth has been killed by frost and then store them in a cool but frost-free place for the winter, planting out in late spring (perhaps starting them off in a greenhouse beforehand)[K]. A climbing plant, supporting itself by twining around the thin branches of other plants[K].
                                                                                 
Propagation                                         
Seed - we have no information on this plant, but, if seed can be obtained, suggest sowing it in a greenhouse in the spring. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant out in spring after the last expected frosts. Softwood cuttings. Division. Dig up the tubers at any time from late autumn to early spring. Store them in a cool but frost-free place and either pot them up in the greenhouse in early spring or plant them directly outside in late spring.

This plant has become naturalised in much of Australia, where it is (like many good food plants)a serious environmental weed. Propagation is simple once the vine has produced aerial tubers. These readily sprout and become new plants, if placed on moist soil. I should like to know if the aerial tubers are edible as well as the fundamental tuber.

The related species, A. diffusa is used for wound treatment (cicatrizant) and has shown very good activity in a recent animal study (J. Nat. Prod., 69 (6), 978 -979, 2006). I have two questions: 1) does A.cordifolia share the same active component with A.diffusa? 2) Can A.diffusa be cultivated as an annual in a temperate region without it becoming a persistent weed?

Recent reports in a NZ paper mentions this "pest" vine may have blood pressure lowering attributes,& rumoured aphrodisiac properties !

I just saw this plant being promoted in the Tokyo plant market as being a Chinese superfood whose leaves can be cooked and eaten. They are calling it okawakame which means literally 'land seaweed' (many kinds of seaweed are eaten here and considered to be beneficial to health as well as a delicacy) They even have a bunch of recepies on their home page ! Many health benefits are cited including stopping bleeding and its use by american troops in Okinawa during WW2. Though it wouldn't be the first 'noxious weed' which has a long and distinguished history of human use...
