How many lychees are safe to eat in a day? What TCM says about the fruit
Traditional Chinese medicine experts suggest no more than 10 to 15 lychees a day for adults to avoid excessive ‘yit hei’ or body heat

Trees across Hong Kong and mainland China’s south are bursting with fragrant, golf-ball-sized red fruit, which can mean only one thing – lychee season is here.
In TCM, lychees are classified as “warm” or “heaty” – a concept known as yit hei (“hot air” – also written yeet hay) in Cantonese that describes a build-up of heat in the body.
According to Karen Cheung, a registered TCM practitioner at Ayla Executive Medical in Hong Kong, eating too many can disrupt the body’s natural balance, leading to inflammatory symptoms. Excess consumption can trigger sore throats, mouth ulcers, acne breakouts, constipation and eczema flare-ups.
