According to a study titled Impacts of turmeric and its principal bioactive curcumin on human health: Pharmaceutical, medicinal, and food applications: A comprehensive review, curcumin poses potential health risks despite its numerous advantages for human health and its well-established safety profile. Individuals’ side effects observed include abdominal pain, nausea, constipation, and hot flashes. According to some accounts, curcumin may cause toxicity under certain circumstances. For instance, individuals receiving doses of curcumin between 0.45 and 12 g may suffer from vomiting, diarrhea, headaches, rushes, yellow stools, and elevated levels of both blood alkaline phosphatase and lactate dehydrogenase. For example, curcumin appears to cause DNA damage at both the mitochondrial and nuclear levels, suggesting that it may have a carcinogenic effect at doses near those that show positive results.
Right way to consume: ½ tsp turmeric in food per day is enough and one should always pair with black pepper for better curcumin absorption. Also, it is best used in warm milk or ghee-based recipes for joint and immunity benefits.
