Hundreds of years ago, scholars observed a fascinating phenomenon: certain fruits, vegetables, and medicinal plants resemble the very organs in the human body they benefit. This concept, known as the Doctrine of Signatures, was studied by ancient researchers such as Galenus, Paracelsus, and Böhme. It later became a core principle in homeopathic medicine.
Today, while modern scientists like Dr. Bradley Bennett from Florida International University emphasize that this resemblance isn’t scientific proof of effectiveness, they recognize its value- especially in developing countries where visual cues help people remember which plants support specific organs or conditions.
These are a few striking examples:
Carrot: A sliced carrot looks like an eye, complete with iris and pupil. Science confirms that carrots support eye health by improving blood flow to the eyes and enhancing their function.
Tomato: A natural tomato has four chambers and is red, just like the human heart. It’s rich in lycopene, which has been found to support heart health and cleanse the blood.
Grapes: A single red grape resembles a blood cell, and a bunch of dark grapes looks like a heart. Research confirms grapes aid heart health and blood purification.
Walnut: Its shape mimics the human brain- with two hemispheres and a grooved surface. Walnuts are rich in serotonin and brain-supporting vitamins. Studies show walnut extract can help improve brain function in Alzheimer’s patients.
Kidney Bean: Named for its resemblance to a kidney, this bean supports kidney function in healthy individuals (according to Chinese medicine). However, those with kidney disease should avoid it due to its high phosphate content.
Sweet Potato: Shaped like the pancreas, sweet potatoes help regulate blood sugar and insulin levels, making them beneficial for those with diabetes.
Onion: When magnified, an onion resembles a single body cell. It is known for helping cleanse body cells of toxins.
Avocado: With its large pit and rounded shape, a halved avocado resembles a womb with a developing fetus. Naturally, it’s known to support hormone balance, aid postpartum recovery, and help prevent women’s cancers. Fascinatingly, it takes exactly nine months for an avocado to mature from flower to ripe fruit.
Figs: These grow in pairs and are full of seeds, symbolizing fertility. They’ve been linked to improved male reproductive health and may help prevent infertility.
In essence, nature may be offering visual clues to the healing potential of its creations. Whether symbolic or scientifically valid, these resemblances continue to inspire curiosity and wonder in the world of natural healing
