Researchers in 2021 have evaluated whether chamomile liquid extract can help with nasal allergy sufferers and determined that it does significantly improve symptoms compared with regular saline nasal spray. Prior studies were only evaluated in animal studies, but this is the first to rigorously test whether it truly helps or not.
The study compared between 4 different test groups:
- isotonic seawater spray with chamomile liquid extract
- isotonic seawater spray
- isotonic seawater nasal irrigation
- nasal steroid spray without nasal washing treatment
Amazingly, the chamomile nasal spray worked better with respect to symptoms and nasociliary function than the other three comparison groups including the steroid nasal spray which is considered treatment de rigueur.
For those who wish to avoid steroids and antihistamines whether due to side effects or for personal reasons, chamomile nasal spray may be worth considering.
You can make it at home adding 3-5 drops of chamomile liquid extract to every ounce of normal saline.
