Potions

Healing Potions, or Potions for short, are a type of medicine widely used in series. They are made by extracting essence from Hipokute Herbs. These magical potions heal injuries instantly with varying effectiveness depending on their potency, making them crucial in a world where physical conflicts happen often.

The Armed Nation of Dwargon used to be the major producer of healing potions, but Tempest has since taken that title after they developed the technology to mass-produce them. They became one of the major exports of Tempest ever since.

Types
According to their potency and effectiveness, healing potions can be divided into 3 types. Lower level potions can be created by diluting superior ones, and using magicule-rich water for dilution can double the yield.

Low Potion
Low Potions are the cheapest and least potent potions produced, able to heal minor to moderate injuries. These potions can be produced by diluting High Potions by 5 times and cost 4 silver coins each when sold in retail.

High Potion
High Potions' potency is somewhere in the middle, able to heal major injuries but unable to restore lost limbs. They can be produced by diluting Full Potions by 20 times, or 98% essence extraction from Hipokute herbs. This is the best potion the dwarves could produce prior to the rise of Tempest. They cost 35 silver coins each in retail.

Full Potion
Full Potions are the most potent potion among all, able to heal fatal injuries and restore lost limbs, even if the limb was lost long ago and became a stump. They are created by extracting Hipokute herbs essence by 99%, a feat unattainable before Rimuru and Vesta developed the process. For some unknown reasons, the 1% difference in extraction efficiency resulted in 20 times difference in potency.

It is known that extraction in vacuum environment is the key to break the 1% barrier. Producing one of these without using skills would take one full day. These potions are not sold openly on the market, and would cost 5 gold coins each when purchased through special processes.

Usage & Limitations
Potions can be drank or applied directly on wounds to take effect. Upon application, the wounds will be healed instantly without leaving even a scar. It appears that Full Potions could read the original body structure and construct limbs out of magicules, hence it could regrow lost limbs irrespective of the time it's lost. Almost all living organisms can be healed using potions, and Full Potions can even regenerate damaged weapons made of Magisteel.

However, since healing potions are magicule-based, they cannot heal people with anti-magicule attribute like Hinata (magicules will get purified upon contact). In the OVA, it is also established that potions promote rapid cell growth (even malignant ones), hence people with malignant tumor might die when a potion is used on them.
