Chapter 4 argues that colonial science medically legitimized and naturalized the care labor of “hardy” South Asian women for “frail” British women, whose white bodies were believed to be debilitated in the tropics. Colonial medics’ race and class anxieties towards brown nursemaids were couched in the scientific language of hygiene. South Asian Brahminical notions of casteism also shaped British medical discourse, making British employers reluctant to employ “low”-caste ayahs and amahs. Bodily anxieties in the imperial home, however, were not experienced by British employers alone. “High”-caste Indian maidservants – sought-after by the British – feared loss of caste purity for working in close proximity to casteless British bodies and for consuming food from the impure British kitchen, and demanded compensation for their caste loss. Despite the tensions of race and caste, British families in remote areas desperately depended on the healing knowledge of their Indian servants. Although British biomedicine marginalized South Asian medical epistemologies (Ayurveda, Unani) as unscientific, Indian nursemaids continued to bring local magico-medical knowledge into the British imperial home.
