. Some modern variants available from pharmacies are made of flexible plastic and can be compressed to exert additional pressure. In recent years alternative strategies have been developed, including bulb syringes in which the flow is created by squeezing a bulb and more advanced 'pulsatile devices' which mechanically pump the saline.
Bulb syringes provide the user with complete control over the pressure. Pulsatile devices either pump at a constant pressure or require the user to turn a control knob. Neti pots, on the other hand, require the user to turn the head (with the neti pot inserted) in order to control the pressure.
Efficacy and Safety
The use of a neti pot requires mixing up a saline solution that will be poured through the nasal passages. A typical saline solution is a mixture of around 500 ml of water with 5 g of salt. Sodium bicarbonateSodium bicarbonate

The practice of using a Neti Pot for nasal cleansing is called Jala-Neti which literally means to cleanse the nose with water. It is still commonly practiced throughout India. In modern times, saline nasal irrigation (SNI) has become more widely accepted as a home remedy to relieve conditions such as allergies, colds and mild sinus infections. Preliminary research indicates that SNI could also be an effective treatment for allergic rhinitis and chronic
