The 1960s hippie-style diet King Charles is convinced he'll beat cancer: Just take cannabis and vegetables

As King Charles III continues his battle with cancer, the monarch is embracing both modern medicine and nature's healing powers by leaning into a "hippie-style" diet of homegrown vegetables and medically-approved cannabis to help manage his symptoms and pain.

The 76-year-old sovereign, who revealed earlier this year that he had been diagnosed with cancer, remains tight-lipped about the specific form of the disease.

Still, he has shared some personal insights about his treatment journey during recent royal engagements. At a Buckingham Palace garden party, the King was heard discussing the importance of diet during cancer treatment with a fellow cancer patient.

"It's sometimes about the diet and what you eat. It can help," King Charles reportedly said to Stamford Collis, a 22-year-old cancer patient and student at Exeter University.

"He was asking me about the treatment I have starting in June and spoke to me about food and diet. He also asked me if I had undergone radiation treatment, which I had earlier this year."

Known for his love of sustainability, organic farming, and holistic wellness, King Charles has reportedly added cannabis to his personal wellness toolkit. A royal insider told RadarOnline.com that Charles is now relying on "two things - vegetables and medically-approved cannabis to treat his anxiety and pain."

"It's a hippie-style diet from the 1960s, but he thinks it is part of the way he will beat his disease alongside chemotherapy," the source said. "It fits right in with his love of holistic therapies and wellness, and at the very least he wants it to help him hold onto his throne for as long as possible."

Courtiers also revealed that Charles has started cultivating his own cannabis crop at Highgrove House, his country estate in Gloucestershire, where he's tended gardens for decades and runs his organic food business. While the crop is described as modest and strictly for personal medicinal use, the symbolism of a reigning monarch growing cannabis is historic.

"He's looked at cannabis as a means of fighting the disease and also of killing the pain," a British royal family aide explained. "He's a very open-minded chap and doesn't shut himself off to any form of cure or pain relief."

The King's embrace of alternative treatments mirrors his long-standing for homeopathy and natural healing remedies. In fact, the palace source emphasized that Charles has "read all the studies around [cannabis's] benefits and is giving it a go."
