The image above is of a plant called Rosemary
These days more and more people are turning to herbal medicines and herbal food supplements. Rosemary is a medicinal plant. Rosemary leaves are sprinkled in food or added to tea for flavour and health purposes.
I suggest you plant your own Rosemary as part of your garden plants. If you have a garden and you don't have this herb please drop by the nearest plant nursery and get one. They will also help you with your queries.
If space is your problem - don't worry - Rosemary does well in a container as long as you expose it to enough sunlight and keep the soil moist. Thank you
