Not only does the molecular composition of something matter, but also the geography, climate, terrain, terroir, season, temperature, and more, amounting to "where" it was sourced from. Take, for tangible example, water. Water from a volcanic island like anything in the Pacific Ocean, Japan for example, has a particular deliciousness making it exceptionally suitable for green tea. The water itself is imbued with minerals and elements. On the molecular or atomic level we might call it water, h2o, but when we look at the varying strata of composition, we find that it does not just have one unique thumbprint/fingerprint for composition at the atomic level, like h2o, it also has many layers at different scales that affect its flavor and effects on the body. Similar to how cotton candy is made, by swirling all the surrounding elements into one substance, naturally occurring resources and fruits/crops are a seamless and edgeless amalgam of their surrounding "context" - constituted by temperature, air density, exposure-to-sun, rock-contents,, the thing itself is woven/weaved from the surrounding space/matter/properties and yields a very specific outcome-fruit.
So when you cover yourself with a blanket your parents bought you when you were a child, you are covering yourself with cotton that grew in a specific climate, in a specific place, with soil and sunshine and water and temperature that baked that cotton plant and made it exactly what it is/was. Growing the same seed elsewhere will not have identical outcomes. If you grow it in a cold place, you will get a different fabric texture than if you grow it in a hot place, or a moist place, or a dry place. And beyond the suitable range for growing, it simply will not bear fruit. We label different crops and resources by the same label and call them "varieties" of one another, but in reality we are simply being lazy with our specificity and our categorization. A plant grown in a hot climate has a tendency to transmit the heat it was gestated/incubated in, and a plant grown in a cold climate has a tendency to transmit and transfer the coolness it was gestated in. These are subtle truths not noticed by the masses - the system of conditions is imbued, is etched, into the summary product.
Consider how certain varieties of wine or lemons or drink are famous specifically because of the origin climate/temperature/soil. Sicilian lemons cannot be grown anywhere, just in Sicily. Champagne is named after the region from which it bears its eponymous name. And it is no secret that two "identical" dishes prepared in two completely different countries will taste very different and have different effects on the body, because the ingredients are sourced locally, and in the sourcing is the makeup, not on the exacting-chemical/chemistry level, but on layers that are subtle -- in the folds between the atom and aspect-of-the-naked-eye, true layers and strata that are largely invisible and untracked, knowable only by the environment which bore/gave-birth-to them.
In certain mystical traditions there is the concept of the "mandala" which is not only the presence in the center, it is the surroundings. Every fruit comes not only from its own inherent properties as encoded in the seed, but also in the soil , the water, the metaphorical sunshine it receives, the steady state temperature of the spot. All these factors constitute what we call the "material."
