How beautiful your spinach has grown, once I bought spinach and lettuce seeds to plant in a pot because I live in an apartment. The lettuce grew very well but the spinach barely sprouted and didn't grow, perhaps they should be sown straight into the ground.
I love spinach in an omelette (egg, potatoes, paprika, onion and garlic) it is delicious and I also like to prepare it with pasta, milk cream and chicken, my daughters love to eat it that way.
The chanca piedras was taken by my father for a while to explure stone from the kidneys but he prepared it as an infusion, I did not know that it could be eaten raw. Your information is very useful, thanks for sharing it.
