The extract from the ficus tree (Ficus deltoidea), called mas cotek in its native Malaysia, has been used for centuries to treat a variety of ailments, from diarrhea to edema. It is also believed to aid in the absorption of nutrients, have anti-aging properties and even increase libido. All parts of the ficus, from berries to roots, are considered useful, and the extract can be taken from dried or fresh parts of the tree.
Use pruning shears to remove a small branch from the ficus tree with leaves and berries still intact. Cut into pieces that will fit in a large pot.
Add 1 1/2 gallons of water to a large pot and bring it to a boil. Place the pieces of ficus into the water and continue to boil for 45 minutes.
Place a coffee filter over a container that is large enough to hold all of the liquid. Pour the water from the pot over the filter carefully and discard the spent pieces of ficus.
Place a lid on the container and store the newly brewed tea in the refrigerator.
