About Karela/Bitter Melon

In India, bitter melon is called Karela.

Bitter melon is also known as bitter gourd, or bitter squash and belongs to the family Cucurbitaceae in which the plants are vines.

Bitter melon originated in India, then spread to China and is now grown all over Asia, Africa, the Caribbean and South America. It grows well in the tropical and subtropical areas.

The fruit is used as a vegetable and is extremely bitter. It has an extremely bumpy and uneven skin and is almost ugly looking. The fruit is eaten when green and mature. It turns yellow to orange when fully ripe with bright red seeds.

Traditionally bitter melon has been used as a folk remedy for a variety of ailments particularly stomach ailments. It also has been used in herbal medicine by the people of Amazon, Mexico, Brazil, Peru and Nicaragua.

Bitter melon is available in capsules and tincture forms. Fruit and seed extracts are also available in tablet and capsule forms. Whole vine powders and extracts in capsule and tincture form are available too.

When cooking the vegetable the bitterness of karela/bitter melons can be reduced to some extent by parboiling or soaking it in saltwater for about 10 minutes. The videos below show two ways bitter melon curry is cooked in India.

Hi Rajan, my friend fasting blood sugar level was 5.8. Actually I have past knowledge of the many wonders Kerala/bitter melon has. So when the results came to be .3 higher, I decided to try this method out. I can only say WOW WOW WOW!! After taking only 4 days her blood sugar went down to 5.2. I think we will try this out for another 3 days and stop for awhile to try this again since I read on other websites that bitter melon cannot be on long term. Yes/No?? Any feedback from you or bloggers will be very much appreciated. By the way, does it also lower cholesterol? Any experience shared here will be great!

rajan jolly. I'm very familiar with bitter melon, and hate it... haha. My wife tries to hid it in food, but I always know it's there. She echoes exactly what you say, it's very healthy for you, but like you said, it does take LOTS of time to adjust your tasted buds to. Voted up and useful.

Paul Richard Kuehn from Udorn City, Thailand on April 23, 2013:


This is an another very interesting and useful hub. I first started eating bitter melon when I lived in Taiwan in the 1970s. It tasted delicious when it was stuffed with pork. I occasionally still eat it in Thailand. Little did I know that it has so many good health benefits. Voted up and sharing with followers and on Facebook. Also Pinning and Tweeting.

Rajan Singh Jolly (author) from From Mumbai, presently in Jalandhar, INDIA. on March 12, 2013:

Sangeeta, to a certain excess yes it does affect the water soluble vitamins. But if you like the slight bitterness you need not do this.

Thanks for reading and sharing.

sangeeta verma from Ludhiana India on February 22, 2013:

Voted up and sharing.

What I feel is soaking it in salt for sometime then wash with plenty of water to remove the bitter taste some nutrionale value too get washed away as most of the vitamins are water soluble , plz clarify my doubt.

Peachpurple, bitter gourd is the same as karela. There are slight differences like color, size ans it may be somewhat less rough in different regions of the world but it has a rough uneven skin, just like a house lizard.

Thanks for reading.
