A four-day fever requires careful attention. In Ayurveda, you can take Guduchi (Giloy) tablets or juice twice daily, as it boosts immunity and helps reduce fever. Sudarshan Ghanvati (one tablet twice a day after meals) is also highly effective in managing fevers. Hydrate well with warm water infused with Tulsi (holy basil) and ginger. Eat light, easily digestible food like rice gruel or vegetable soup. Since the fever has persisted for four days, it is very important to consult a physician to identify the underlying cause and ensure there are no complications. Please seek immediate medical care if you experience severe headaches, rashes, or breathing difficulties.
