Pokka Corp has announced plans to market a drink that can ease hay fever symptoms. The Japanese soft drinks maker said earlier this week that it will begin to market the lemon-based beverage from 10 January.

Following laboratory tests, Pokka said, hesperidin - a substance found in the peel of most citrus fruits - contained in lemon polyphenol has an anti-allergic effect that alleviates hay fever symptoms.

A 100ml bottle of the soft drink, which will be priced at JPY162, contains 400mg of lemon polyphenol. Pokka hopes for first-year sales of JPY200m.
