This is really sour!
Of course, we do not want to consume Oxalis latifolia Kunth (in Nepali: Chari amili/amilo) in bulk. However, life is adventure. We should try this. Eating cleaned leaves, shoot and root of this wild herb provides strong sense of sourness to our buccal cavity. Human nature of exploring and adventures has been key element in human learning for survival and growth.
Doing nature exploration with kids is one of my strategy of environmental education from a parent's side. In nature, we should really be wary of risks associated with exploration that range from toxicity and allergies to infections and impact injuries. However, as a parent, I have little more leverage than schools in taking decisions for my kids. This is called 'risk taking'; and I love it to teach the same (safety limit is mandatory!) to my kids, be it navigational or sensorial.
When it comes to comsuming Chari amili/amilo, I used my own childhood experience to make my kids savour few shoots of the herb once in a while. When I was a kid, I used to eat the whole herb with other kids. My kids also do not hesitate to eat Chari amili (as we say in our local Nepali dialect) in controlled amounts (they know that eating this in more amount is not safe).
