Thanks for trusting Ayurveda and specific terms like stanya and blood shuddhi by specific drugs yeah it's right u can do it but choice of drug is matter of expertise on examination of stanya and blood (expression sites like lips, soles of palms feet, medra mani i.e. glance, nasagra, netra,face and skin) as well and what's it offering to ur infant and skin
Next Steps
till u consult Ayurveda Dr plz apply neem leaves paste on ur affected skin n wash with alum soap, avoid curd n salty snacks late night dinner
