King Charles's favourite drink that 'boosts heart health and helps lower blood pressure'

is celebrating his 76th birthday today, and it's believed he'll be starting the celebrations with a cup of his favourite health-boosting tea.

The UK Loose Leaf Tea Company describes this tea as having "a delicate taste" with flavours of wildflower honey and muscatel.

While tea connoisseurs suggest that the first flush of Darjeeling should be savoured without milk, the second flush has stronger flavour and higher tannin content that milk can reduce.

Beyond its distinctive flavour, Darjeeling black tea is touted for its numerous health benefits when included in a balanced diet.

indicates that teas from the Camellia sinensis plant, such as Darjeeling, are rich in beneficial plant compounds like Polyphenols and Phytochemicals, including flavonoids.

Julian Payne, his former press secretary, has shed light on the monarch's dining quirks telling The Mirror: "An early lesson I learnt when out on the road with him was to have a big breakfast or bring a few snack bars with you to keep you going.

"The working day is pretty relentless. Beginning with the radio news headlines and a breakfast of seasonal fruit salad and seeds with tea."
