Mashua
Tropaeolum tuberosum
High in the Andes, mashua has been grown alongside potatoes, oca, and ulluco for thousands of years, prized as one of the hardiest tubers a family could plant when frost threatened everything else. Andean healers traditionally turned to the boiled tuber and its broth as a folk remedy for kidney and bladder complaints, and the plant carried a curious reputation as a calming, appetite-suppressing food. Inca chroniclers wrote that the tuber was served to soldiers and even to royal court attendants specifically to dampen their desires, a belief that has followed the plant for centuries. Today it remains a beloved market vegetable in the highlands, valued as much for its resilience in poor, cold soil as for its old medicinal lore.

Traditional preparations.
A simple, warming preparation drawn from Andean kitchen tradition, where the cooking broth itself was sipped as a folk remedy for urinary discomfort.
Peel and slice about 3 ounces (roughly 100 g) of mashua tuber and simmer in 2 cups (500 ml) of water for 15 to 20 minutes, until tender. Drink the broth warm and eat the softened tuber as a simple side dish.
A mild, lesser-known infusion made from the peppery leaves, used occasionally as a folk tonic in the highlands.
Steep 1 teaspoon of dried mashua leaf in 250 ml of just-boiled water for 8 to 10 minutes, then strain.
Safety.
Mashua is traditionally eaten cooked rather than raw, since raw tubers have a sharp, peppery bite from glucosinolate compounds. Some research suggests it may have mild anti-androgenic or libido-dampening effects, so those trying to conceive, managing hormone-sensitive conditions, or who are pregnant or breastfeeding should stick to ordinary food-level amounts.
