It’s estimated seven out of ten Ecuadorians use medicinal plants. Ethnobiologist Omar Vacas has spent 15 years researching local flora used for centuries to cure diseases. He published an article about traditional medicine used by the Kichwa people in the Napo jungle province. He says the Kichwas are often unaware that this info can be useful in developing pharmaceutical drugs. For example, balsa can reduce labor pains. There are 23 conditions including toothache and rheumatism that can be cured by plants used by the Kichwas. These include uña de gato (cat’s claw), ortiga brava, achiote de venda, palo de tortuga, sábila (aloe), ruda, dulcamara, sangre de drago (dragon’s blood), chancapiedra, chaya, valeriana, boldo, condurango and zarzaparrilla.
