Leech Blood — Detailed Guide
Blood from leeches and more
In ARK: Survival Evolved and ARK: Survival Ascended, Leech Blood is collected from the bodies of creatures: the ARK Wiki names the 
Leech, the 
Lamprey and the 
Deathworm, which you kill and then harvest. The game describes it as "A congealed glob of Leech Blood. Can be used for medicinal purposes when carefully prepared."
Antidote ingredient and fishing bait
The wiki lists one crafted item for it, the 
Lesser Antidote, where horns from a Deathworm or 
Woolly Rhino are accepted instead. It also works as bait for fishing, as an alternative to 
Sap or 
Giant Bee Honey. You can eat it, though the wiki has no record of any effect or disease symptoms afterwards.
Harvesting it in the swamps
The wiki suggests sailing into the swamps on a 
Wooden Raft that has an open deck as well as a room:
- Kill the leeches from the deck with a crossbow, or another ranged weapon if needed, so they cannot attach to you, then collect the blood with a
Metal Hatchet. - Keep a campfire lit in the room; it burns off leeches that do latch on and can cook the prime meat of a
Titanoboa. - If a Titanoboa approaches, hide in the room and fight it with a melee weapon once it clips inside.
- A raft not built from stone is at risk from
Sarcos, which deal decent damage to wooden structures.
The other route is riding a 
Rex into the swamp and killing the leeches from its back; any carnivore works, and riding keeps leeches off you. Then harvest with the mount or a hatchet. Choose a mount too big to be carried, so a 
Kaprosuchus cannot grab it; the wiki recommends a Rex or 
Spino. On Aberration, lampreys in the blue zone are another source.
Spoilage, storage and weight
Leech Blood spoils after 3 hours. The wiki notes that a 
Preserving Bin can hold it without lengthening that time, and that it cannot be put in a 
Refrigerator, even though patch notes 242.3 say it can. Each glob weighs 0.2 and they stack to 50, so a full stack weighs 10. Our records list it on 14 maps and count 82 loot crates that can contain it, Aberration Blue and Aberration Purple among them.
