  3. Flowers: Neem flowers are known for their calming and antipyretic properties. They are often used to balance the pitta dosha.
  4. Seeds and Oil: Neem seeds and the oil extracted from them are potent in treating skin conditions, dental issues, and as a natural insecticide.
  5. Fruit: The fruit is used in anti-parasitic and antifungal treatments.
  6. Twigs: Twigs are traditionally used as a natural toothbrush, promoting oral health due to their antibacterial properties.
  7. Root: The root is used in treating gastrointestinal and respiratory conditions.
