  • Juice (Svarasa): 10 to 20 ml (fresh leaf juice).
  • Oil: External application or 5-10 drops internally as directed.

9. Safety Information

Neem is generally safe when taken in recommended doses. It is widely used in formulations for both children and adults. However, due to its cooling and drying nature, it should be used with specific vehicles (Anupana) like ghee or warm water to prevent aggravation of Vata in susceptible individuals.

10. Side Effects

  • Vata Aggravation: Excessive consumption may increase Vata, leading to dryness or fatigue, due to its Ruksha (Dry) and Sheeta (Cold) qualities.
  • Gastric Upset: The intense bitter taste may cause nausea or vomiting (Vamana) in some individuals if taken in large quantities on an empty stomach.

11. Precautions

  • Pregnancy: Caution is advised. Neem is generally avoided or used under strict supervision during pregnancy due to its strong detoxifying and "sharp" nature.
  • Hypoglycemia: Diabetics on medication should monitor blood sugar, as Neem lowers blood glucose levels.
  • Vata Prakriti: People with a Vata-dominant constitution (dry skin, lean body) should use Neem cautiously or balanced with unctuous substances like Ghee (Ghrita).

12. Storage Instructions

  • Store dried leaves or bark powder in a cool, dry place.
  • Keep in an air-tight container to prevent moisture absorption.
