I had a friend over the other day. I have a biggish garden. I took her round and she spotted atleast half a dozen plants that have health properties which I thought were weeds. There was this creeper with heart shaped leaves that was so to say invading my garden. She knew the name and she said it is called Amruthavalli having properties to cure diabetes. Then there was another one called vitamin leaves which she said was rich in vitamin C It is always good to call an expert before we uproot plants that we assume are weeds.
