Yesterday, I went back to my hometown to root up the weeds at the backyard. There were some ripe tiny tomatoes, so I picked them up. I washed them clean and soaked them in water. Before dinner, I put these tomatoes in my mouth. Later, I found I got a mild stomachache and made me sort of suffered. I thought the disaster could be caused by these tomatoes. Fortunately, after I finished dinner, the stomachache disappeared. If this stomachache had kept on, I would not have had a peaceful night.
My conclusion: Firstly, naturally grown ones are not guaranteed to be harmless. Secondly, eat tiny tomatoes only after meals and never eat them before meals.
