Earl Grey tea
History
The Earl Grey blend is named after the 2nd Earl Grey, British Prime Minister in the 1830s and author of the Reform Bill of 1832, who reputedly received a gift, probably a diplomatic perquisite, of tea flavoured with bergamot oil, taken from bergamot, a citrus fruit typical of Southeast Asia and grown commercially in Italy.
According to one legend, a grateful Chinese mandarin whose son was rescued from drowning by one of Lord Grey’s men first presented the blend to the Earl in 1803. The tale has no basis in fact, as Lord Grey never set foot in China and the use of bergamot oil to scent tea was then unknown in China.
Jacksons of Piccadilly claim they originated Earl Grey’s Tea, Lord Grey having given the recipe to Robert Jackson & Co. partner George Charlton in 1830. According to Jacksons the original recipe has been in constant production and has never left their hands. Theirs has been based on China tea since the beginning.

Use as a flavouring
Earl Grey flavour KitKat (Japanese)
Earl Grey tea is used as a flavouring for many types of cakes and confectionery, such as chocolates, as well as savoury sauces. For sauces, the flavour is normally created by adding tea bags to the basic stock, boiling for a few minutes and then discarding the bags. For sweet recipes, loose tea is often added to melted butter and strained after the flavour is infused.
Toxicology
In several studies, application of high concentrations of some brands of bergamot oil directly to the skin was shown to increase redness after exposure to ultraviolet light, however this should not apply to ordinary oral consumption of Earl Grey tea. Bergamot is a source of bergamottin which, along with the chemically related compound 6,7-dihydroxybergamottin, is believed to be responsible for the grapefruit juice effect in which the consumption of the juice affects the metabolism of a variety of pharmaceutical drugs.
In one case study, a patient who consumed 4 liters of Earl Grey tea per day reported muscle cramps, which were attributed to the function of the bergapten in bergamot oil as a potassium channel blocker. The symptoms subsided upon reducing his consumption of Earl Grey tea to 1 liter per day.

^ a b c Dr Muiris Houston (September 30, 2002). “Have your cuppa, but go easy on the Earl Grey”. The Irish Times. “…having read a case report in the Lancet titled: “Earl Grey Tea Intoxication”. An Austrian doctor describes the case of a 44-year-old man who suffered muscle cramps. He had been drinking four litres of black tea every day over the past 25 years. However, one week after changing to Earl Grey, he noticed repeated muscle cramps in his right foot. After five weeks the cramps had spread to his left foot, both hands and his left calf … Convinced that it was the change of tea, he decided to stop drinking Earl Grey and reverted to pure black tea again. One week later, his symptoms had completely disappeared. The solution to this case lies in the composition of Earl Grey tea. As well as black tea leaves, it contains essence of bergamot oil, which has a pleasant, refreshing scent. Bergamot contains the psoralen derivatives bergapten and bergamottin. The adverse effects of bergamot oil in this patient are explained by the action of bergapten as a potassium channel blocker within muscle cells. By interrupting the normal flow of potassium, the cells become hyperexcitable, leading to the visible movements and cramps within the muscles. By drinking four litres a day of Earl Grey (equivalent to at least 16 cups of tea), the Austrian man was simply overdosing on essence of bergamot.”

Philippine Daily Inquirer. “Stephen Twining traced back his family’s business to the 1700s, when coffee houses as meeting places were the vogue. How ironic that it was in the company’s coffee house where tea was introduced. Earl Grey tea makes Stephen Twining wish he could move back time because the company did not lay claim to the formula, or the name, when they had produced the blend for the British Prime Minister who was known as the second Earl Grey.”

The Guardian (London). “The original secret formula for Earl Grey tea is changing hands after 155 years with its sole proprietors, the Jacksons of Piccadilly tea merchants… with the sale goes the special recipe of the Earl Grey blend which was entrusted to Robert Jackson’s partner, George Charlton, in 1830 by the second Earl Grey. To this day the formula – which mixes black China tea with other unknown teas – has remained unaltered.”
