A tiny berry with a taste-changing trick.

At first glance, the miracle berry (Synsepalum dulcificum) looks like an ordinary tropical plant. But its small, bright-red fruit has a remarkable ability to change how we experience flavour.

Native to tropical West Africa, the miracle berry produces a protein called miraculin that interacts with the sweet taste receptors on our tongues. After eating the berry, sour foods can taste surprisingly sweet. A squeeze of lemon might taste more like lemonade.

The effect is temporary, typically lasting from around 30 minutes to two hours.

Beyond its novelty, miracle fruit has also attracted interest in its potential to help people experiencing taste changes during cancer treatment. Some patients undergoing chemotherapy report that foods taste unpleasant or metallic, making eating difficult. The miracle berry fruit has been used as a tool to improve the taste of food and make mealtimes more enjoyable, and research is ongoing.

The plant is an evergreen shrub with glossy green leaves, delicate white flowers and oval red berries. It thrives in warm, humid conditions and acidic soil, making it well suited to tropical growing environments.

This ordinary-looking plant has some remarkable abilities! Come see it for yourself in our Fabled Woods display now until November 29.
