Bottle gourd/Lauki/Suraikai juice is a healthy drink. Now it is found that if the juice is bitter in taste, it is dangerous and may cause death. So before drinking bottle gourd/lauki/suraikai juice, just taste a drop first and if it is bitter in taste, do not drink this juice.
Bottle gourd is known as Suraikai (சுரைக்காய்) in Tamil and as Lauki in Hindi.
I have noticed even Cucumber, Snake gourd, Ridge gourd taste bitter sometimes. It is better to avoid these vegetables also if you find it bitter in taste.
