Fruit Seeds Germinating Inside the Human Body

It is extremely rare for fruit seeds to germinate inside the human body, but there have been some extraordinary cases reported about the avocado.

The human digestive system is a complex and harsh environment. Stomach acid, digestive enzymes, and the peristaltic movement of the intestines all work against the survival and germination of seeds. However, the large and hard - shelled seeds of avocados have a relatively high chance of passing through the digestive tract intact compared to many other seeds. There have been a few anecdotal reports where an avocado seed, after being swallowed, managed to lodge in a part of the digestive system where the conditions were less harsh. In these rare situations, if the seed remained in a moist and relatively stable environment for an extended period, and if it had not been damaged during the passage, it might start to show signs of germination such as the beginning of root or sprout development.

Another fruit that might seem possible in theory is the cherry. Cherry pits are hard and can sometimes pass through the digestive system without being crushed. In very rare circumstances, if a cherry pit were to get stuck in the appendix or a diverticulum (a small pouch in the colon), and if the right combination of moisture, temperature, and lack of digestive action occurred, there could potentially be a very small chance of germination. But it's important to note that these are extremely rare and almost anecdotal events, as the human body is generally not a suitable environment for most plant seeds to germinate.
