Many beautiful, interesting, and strange plants live on our planet. One very unusual species is the Socotra Island dragon blood tree, or Dracaena cinnabari. This tree not only has a very distinctive appearance but also releases a red sap, or resin, that is known as dragon’s blood. People have collected and used the resin for many years.
According to legend, the first dragon blood tree was created from the blood of a dragon that was wounded when it fought an elephant. Like the unfortunate dragon, the tree secretes its resin when it’s injured. In ancient times, the resin was believed to have magical and medicinal properties. People used it as a pigment for art, a dye, and a medicine. Dragon’s blood is still used for these purposes today.
Socotra Island is part of an archipelago off the coast of Yemen and Somalia. A fascinating and unique group of plants and animals live on the islands of the archipelago. Conservation of these organisms is very important for maintaining the Earth’s biodiversity.
Rakta is a Sanskrit term meaning “colored” or “red.”
According to Ayurveda, it is one of the seven tissues of the human body. Rakta represents the blood, mainly the red blood cells. Rakta tissue oxygenates the cells, nourishes the body and is thought to preserve life. It originates in the liver and spleen and its waste product is bile.
Blood Falls, in East Antarctica’s McMurdo Dry Valleys, looks like slowly pouring scarlet-red blood, staining snowy white Taylor Glacier and Lake Bonney below.
The trickling crimson liquid isn’t blood, however. Nor is it water dyed by red algae, as early Antarctica pioneers first speculated. In fact, the brilliant ochre tint comes from an extremely salty sub-glacial lake, explains Quora user Aditya Bhardwaj.
About two million years ago, a hyper-saline body of water became trapped beneath Taylor Glacier, isolated from light, oxygen and heat. As the saltwater trickles through a fissure in the glacier, it reacts with the oxygen in the air to create this spectacular, rust-hued cascade.
