Medicinal Uses

In folk medicine, an infusion made from the leaves and fruits, and a decoction from the roots, are drunk by nursing women in order to increase milk secretion (latex from the plant contains the ‘lab’ ferment). The infusion is drunk immediately; the decoction is often added to the water
for brewing maté. The latex is used as a mouthwash to relieve toothache or to encourage the falling off of teeth (antiodontalgic). In order to stop the spreading of venom, in cases of snakebite, it is recommended to employ the stalks to make tourniquets (Martínez-Crovetto, 1981)












Other Uses

    It is highly poisonous too.
    „ The NSW Government’s Department of Primary Industries confirmed that the moth vine is poisonous.“

        the nsw govt and most govts in Australia call many wild edibles that are consumed by millions of people around the world ” poisonous.” In face, the list of delicious, nutritious wild edibles that I have enjoyed, that our govt calls poison keeps growing. Australia is the world’s highest per capita user (and thru our superanuation biggest funder) of glysophate and I dont believe it is a coincidence. I saw an early TAFE Bushcare/Landcare textbook from the 70s in which Monsanto’s Roundup product was the only Trademarked product listed throughout. Therefore I believe our govt cannot be trusted when it comes to getting the right information about the nutritional and medicinal value of wild edibles.
