Signature theory: what looks like an organ is also good for it?

Signature theory claims that foods that look like organs are also healthy for them. This is not an invention of modern times. Even in ancient times, there were healers and doctors who prescribed vegetables and fruits for specific organs. However, the term was first formulated by Giambattista della Porta.

Are walnuts really good for the brain? Ginger for digestion and asparagus for asparagus?

This is behind the Signature Doctrine

The Signature Doctrine was first written down by physician and alchemist Giambattista della Porte, who lived between 1538 and 1615. The doctrine postulates the connection between organs and their natural counterparts. Can one really tell from the shape of vegetables and fruits their meaning for the respective organs?

1. The doctrine of signatures connects the fields of botany, astronomy and geology. But only the branch of food will be discussed here.
2. Walnuts, for example, contain a lot of omega-3 fatty acids, which are particularly good for the brain. Carrots are rich in beta-carotene, which strengthens vision. The tomato with its various chambers not only looks like a heart, but actually offers a lot of potassium, which strengthens the heart.
3. And so there is a whole cornucopia of foods that have a special significance for the various organs.
4. To date, there is no scientific evidence of the effectiveness of each food on their organic counterparts. For example, the walnut is actually rich in omega-3 fatty acids, but other foods such as canola oil, fish and chia seeds also provide this unsaturated compound in abundance. To postulate this ability to the walnut alone is simply wrong.
5. And so it is with all vegetables and fruits to which the various benefits are attributed.
