It is beneficial in:

• Mānasa vyādhi (Anxiety, depression, emotional instability)

• Nidrā-nāśa (Insomnia, disturbed sleep)

• Chittodvega (Stress, irritability)

• Unmāda (Psychosis, hysteria)

• Apsmāra (Epilepsy, seizures)

• Śiroroga (Headache, migraine)

• Raktapitta (Pitta bleeding disorders)

• Kushta (Skin eruptions aggravated by stress or Pitta)

Externally, Jatāmansi oil is used for scalp and nervous system health — promoting hair growth, relieving tension, and inducing calmness.

Pharmacological Insights
