This technique is used to suppress technique-induced marks on a person. Marks of weaker power can be completely suppressed by this technique alone, but for marks of higher power like Sasuke Uchiha's Cursed Seal of Heaven, causes the seal's power to become dependent on the recipient's own willpower to some extent, especially if the sealer is not experienced enough to strengthen the seal with his own power. It is also capable of holding back certain kekkei genkai, such as that of the Kurama clan as seen when Kurenai tried to do this.
This seal requires a high number of hand seals and a large amount of chakra to be performed. Preparation for this technique requires two concentric circles with kunai placed in intervals along the circumference, in addition to a number of characters written in blood that radiate out from the centre of the cursed seal.
According to Kakashi, this technique is quick, but painful. The seal can be removed at any time by the caster or whoever the seal is on, as demonstrated during Sasuke's battle with Naruto in the Valley of the End. Since this seal relies on the will of the individual on whom it is placed, the affected may be able to just will it away without an unsealing technique.
When Orochimaru was extracted from Sasuke through Itachi's Sword of Totsuka, not only was the Cursed Seal of Heaven removed, but also the Evil Sealing Method around it.
