Besides coconut, wax gourd, neem tree is a kind of plant that Cambodian uses to treat high temperature.
It is a traditional treatment and still useful until today.
There are three ways of usage:
1. Be a salad
Cambodian usually mixes neem flower with fish, some green vegetable, ripe tamarind, sugar and fish sauce to be a food - Cambodian salad.
It is a way to prevent body from getting high temperature.
Mostly, this food is favorite of middle age and elder age; the young does not prefer it because it is bitter.
Neem tree is seasonal plant.
When there is no flower, Cambodian will use its young leaf to replace. However, the flower is best.
2. Boil leaf
I have heard in the past, when health science did not reach Cambodia yet, Cambodian people with fever put neem leaves in water pot and heat until the water was boiled, then they drank it.
3. Chew leaf
Some people don't boil or make food; they take young leaf from neem tree then chew it. It is believed to have effect in treating fever too.
I asked how many leaf to take, my family told that Cambodian prefers seven leaves - but they are not sure.
Though today we have medicine to cure fever, still custom of using neem tree is in mind of Cambodian, especially people living in rural area and people that have no money. As for people living in city, they like to use neem's flower/young leaf to be food.
