Turmeric as an antioxidantFeatured science projectScience project video


This science fair project was performed to study the effectiveness of turmeric as an antioxidant. The test was done using Perchlorate as an oxidant on Daphnia, and countering its effect using turmeric juice.


Turmeric juice is able to counter the effects of exposing daphnia to perclorate solution.

Scientific Terms

Turmeric, antiseptic, antioxidant, anti-inflammatory, oxidization, perchlorate, oxidizer, hyperthyroidism



Turmeric is a herb that is similar to ginger and is used in curries to give it a peppery flavor and yellow color. It is also known to have many medicinal properties and is widely used as an antiseptic in Indian and Chinese traditional medicine. It has been used to cure digestive problems, stomach aches and nausea.

Turmeric has the elements of both an antioxidant and an anti-inflammatory. It has been found to be useful in treating inflammations, arthritis and even preventing the spread of certain types of cancer. As a strong antioxidant, it also protects the cells in our bodies from damage by oxidation. The antioxidant properties of turmeric protect our brain, liver and kidney from damage from drugs, chemicals or alcohol.


Perchlorates are salts that are obtained from perchloric acid. It is a reactive oxidizer and is known to obstruct the intake of iodine intake by our thyroid glands. This causes health problems because the thyroid gland releases hormones that control our rate of metabolism. Perchlorates are also used as medication to treat hyperthyroidism.
