Averrhoa carambola has been used to polish and
clean metals for centuries due to the acidity of its
fruit
juice. It does a very good job at removing rust from the
metal. The juice can also be used to remove rust stains from
white cloth.
Wood from the Averrhoa carambola tree is used to make furniture, and
in construction.
In India, when the roots are combined with sugar it is considered an antidote
for poisoning. Also, when the fruit is ripe it is given to patients with
hemorrhages, which reduces the bleeding or even halts their hemorrhages altogether. The
fruit has also been dried out and given to patients to counteract fevers.
In Brazil, Averrhoa carambola is commonly used as a diuretic.
