King Charles' coronation oil 'concocted for 8 months on housing estate

"He was even careful to ensure he replaced any animal-derived products on the ancient shopping list with synthetic versions."

Soo..... He goes to great lengths and takes 8 months to source the ORIGINAL ingredients..... Just to new age vegan it with synthetic chemicals.

Why not just buy some stuff off the shelf? Seems like a bit of a concocted process to end up with a sham product.
