Yes, Taro, Eddo and Dasheen are all cultivars of Colocasia esculenta, Cultivars have been bred to reduced the toxin oxalic acid. The corms of all three cultivars are at safe levels obviously or they would not be sold retail. The leaves on the other hand of eddo still contain inedible levels of Oxalic acid while the leaves of Dasheen are used to make the Trinidad and Tobago version of Callaloo. There are likely more sub-cultivars under the generic name Taro that I would not assume editability of the leaf.
