Individuals who are taking blood-thinning medications, such as anticoagulants or antiplatelet drugs, should exercise caution when using turmeric, as it can have mild blood-thinning effects. Additionally, people with gallbladder issues or those prone to kidney stones should consult a healthcare professional before using turmeric, as it might exacerbate these conditions. Pregnant and breastfeeding women should also seek medical advice before incorporating turmeric into their diets due to its potential effects on hormonal regulation.
