my spanish friend eats cooked nightshade leaves and isnt poisened. she calls it mora. how is that possible?

Answer 1

The Nightshade family is absurdly large, incompasing many genera of many plants. You would have to be more specific as to the plant. The leaves of Datura or Brugmansia are particularly toxic. Nicotiana (tobacco) is also toxic. The tomato, potato, eggplant, and many pepper plants are also members of the Nightshade (solancea) family, and all have edible parts that are not toxic. So, depending on what the plant is, the leaves may not be toxic at all. Also, as mentioned above, the method of cooking may effectively isolate and remove any toxins, as most are highly solluble in water. There are no mushrooms in the nightshade family. Mushrooms are in the Kingdom Fungi.

Edit:
There is a genus of plants known as "Mora," however these are not in the Nightshade family.

Answer 2

this was very commen in the old days for women to eat belladona, it contains atropine which dialates the pupils(this is to make a women more attractive). there are lots of poisions in the plant as well like conine which is like strycnine(used to pass off as lsd, causes the muscles to contract and spasm) its deffintely not something to do in large amounts or for long periods of time.
She may have built up a tollernce. I would not suggest trying it hallucinations are quite possible and unknown amounts could cause death. I guess for your freind all things are good in moderation.

Answer 3

It probably has to do with the cooking process. If they are boiled, the toxins may be removed in the process. Seems risky though, The Japanese eat a puffer fish called fugu- if not prepared properly it can paralyze or even kill you.

Answer 4

I believe that the deadly nightshade is a mushroom. Mushrooms don't have leaves. I wouldn't eat dinner at her house, though.
