Which place is famous for litchi in India?

Muzaffarpur is famous place for litchi cultivation. Muzaffarpur is best known for good quality of litchi production in India and worldwide (Muzaffarpur is one of 38 districts in Bihar and part of Tirhut subdivision.).

Shahi litchi is good varieties of litchi, are grown mainly in Muzaffarpur district and adjoining areas of, Vaishali, Begusarai, Samastipur and Begusarai districts.

Muzaffarpur produces Shahi, China and other varieties of litchi, but Shahi litchi of Muzaffarpur is very popular. It has always a high demand in other states of India as well as abroad. It is called Shahi litchi in Muzaffarpur( Bihar) because of its unique aroma or scent.

 Fruit weight ranges from 20-15 gm. Muzaffarpur Shahi litchi gets matured in the last week of April. One tree of litchi produces approx 150 kg of fruits. (min-100 kg, max 150 kg).

One fact I also want to include here in respect of Muzaffarpur Shahi Litchi that it has got GI tag. (GI tag is given to a product for its specific geographical origin ).

Muzaffarpur Children death (Litchi Poison )

Recently, the whole country was stunned at the incident that caused more than 150 death in innocent children in Muzaffarpur overnight. The number of children fallen ill was twice the number of children who died. 

Since casualty took place in the month of April-June. Generally, lychee is harvested during this period in Muzaffarpur and adjoining areas. Everyone connecting it with litchi. But there was no solid point was given by anybody to justify it until Dr.T Jacob John wrote an article in the newspaper.

Dr. T Jacob John a retired professor of virology CMC Vellore confirmed a toxin found in Litchi, that cause death in a malnourished child. Actually, in 2012-13, a two-member of Indo-US Virologist headed by DR Jacob suspected and confirmed, a toxin found in litchi that caused to hypoglycaemic encephalopathy. This toxin is called methylene cyclopropyl glycine (MCPG)

Actually, litchi’ toxin (MCPG) develops hypoglycaemic encephalopathy in a malnourished child. Don’t be confused with encephalitis.

Here one thing to be noted only malnourished children between two to ten years of age were affected by hypoglycaemic encephalopathy.

A malnourished child who eats litchi and goes to bed on an empty stomach tends to develop hypoglycaemic encephalopathy.

The reason is simple, Your brain needs a normal level of glucose in the blood to work properly. Whenever your blood run short of normal glucose level, glycogen ( reserved glucose in the liver) broken down into glucose and fulfill shortage.

Malnourished children who had eaten the only litchi and gone to sleep with an empty stomach at night develop hypoglycemia (A condition when the blood glucose level is too low). A toxin in litchi blocks the alternate supply of glucose to the brain. Thus malnourished children develop hypoglycaemic encephalopathy.
