There are two natural medicinal/food that we can rely on these days: Coconut and Malunggay.
Coconut where you get coconut juice, coconut vinegar, virgin coconut oil, etc.
Malunggay which you can cook, as always, juice, dried.
I believe these are the two things that we should not run out of if you live in the province or, you have a bigger vacant space. But if you have a very small vacant space, please don’t miss out on malunggay. Plant it even on half drums.
