Citronella can be soaked in water for a long time, but the following points should be noted:

1. Choose fresh citronella, and the citronella in good condition will taste better when soaked in water.

2. Wash citronella to remove dirt and impurities.

3. The soaking time should not be too long, and it is suggested to be about 5- 10 minutes.

It is recommended not to drink citronella water for a long time, and it is best to stop it every once in a while to avoid adverse effects on the body.

5. If you have allergies or other unwell symptoms, you should stop drinking lemongrass water and seek medical advice in time.
