A French company has brought out a new seaweed tea line, which could double as a bath additive.

Kusmi Tea, which produces an extensive range of black and green tea blends baroque packaging, has launched a line combining seaweed and green tea with spearmint in a 125g box.

Available initially in France, the product was unveiled at the Sial Food Show in Paris this week. The brand is stocked in the UK by Harrods and the Conran Shop.
