Known Hazards

Although no specific mention has been seen for this species, plants in this genus can contain quite high levels of oxalic acid, which is what can give their leaves an acid-lemon flavour. Perfectly alright in small quantities, leaves containing oxalic acid should not be eaten in large amounts since it can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[

The vernacular name of the plant used by the Sambaa people located in Western Usambara is "mnywanywa"

I was told this by Dr.Shunda, the ethnobotanist working in that place during my field practical.
