What causes the sap on a Linden tree? and what can I do?
There is a tree in the tropical rainforest that has a black sap that oozes out of the tree. Touching the sap will cause burn type sores on the skin.

yes, all trees do produce sap. you have to think of sap as the blood of a tree. the sap is found just under the bark of the tree. the sap flows up the tree to nourish the tree. you will not find the active flowing sap in the hard wood of the tree. this is why if you cut a thin line of bark around the base of the tree, the sap would not be able to flow up to the leaves and branches and will not be able to nourish itself and will whither and die. different types of trees have other types of sap such as latex but all trees have sap. only maple trees produce sap for maple syrup.
Leaves are kept alive by the sap from the tree.
Taking your question literally, these leaves are edible, the Little Leaf Linden or Lime Tree, the Fragrant Spring Tree from Japan and the Mulberry. There is also a Chinese tree called the Goji No. The fruit of a tree is the seed containing capsule. The leafs are the foliage edible or not.
During the season of autumn, also called fall.More detail:As the temperatures get cooler, and the days get shorter, the tree sap goes down. The changing color of the leaves is due to reduced light, cooler temperatures, and the sap falling. After the color of the leaves change, they then begin to fall off. This is nature's way of helping the tree survive the cold temps of winter. The nutrients and water are then utilized in feeding the tree and keeping it healthy since there are no leaves to leach the nutrients from the tree.
When a tree drops it's leaves in autumn the seal that causes the leaf to drop is the leaf scar. This seals and prevents loss of sap.
Lick the sap off of the tree.
I think the better question is: why do you have tree sap in your hair?
