Incense, candles and potions are commonly used coupled with a specific spell to summon a spirit. – Pad of Definitions (2.01 In My Time of Dying), Official Website

Summoning Spells

Demon

As seen with Trevor and Nora in 5.12 Swap Meat, summoning a demon requires a bowl of unknown herbs, set a top the Sigil of Baphomet, with candles placed on each point of the pentagram. Once the altar is set-up, an invocation in Latin must be spoken:

Attenrobendum eos,
ad ligandum eos,
potiter eos,
coram me.

Once completed, any demon who hears the invocation will manifest in the nearest vessel.

Azazel

John summoning Azazel.

John Winchester uses a special summoning ritual to make contact with the demon Azazel in 2.01 In My Time of Dying. Some of the required ingredients for the ritual were: blood of the summoner, acacia, oil of Abramelin, six lit candles positioned on the Sigil of Azazel, and an Latin incantation:

Attenrobendum eos,
ad consiendrum,
ad ligandum eos,
potiter et solvendum,
et ad,
congregontum eos,
coram me.

Crossroads Demon

The standard method of summoning a crossroads demon is fairly simple. the ritual first requires the summoner to bury a box/container in the middle of a crossroad. The contents of the box must include graveyard dirt, a black cat bone, and a photograph of the person wishing to make a deal. Yarrow flowers being planted at the crossroads helps in the ritual, though appears to not be a necessary component.

Death

Death, having been locked away by God for hundreds of years is released by Lucifer in 5.10 Abandon All Hope. Lucifer performs the ritual to raise Death in Carthage, Missouri on William Jasper's Farm, which was the site of the Battle of Hellhole during the Civil War.

The ritual required the deaths of all the women and children in the town, who were then buried in a mass grave on the farm. Their deaths were then followed by the sacrifice of the townsmen and the demons possessing them.

Bobby and Rufus summoning Bobby's Reaper.

Reaper

While lying in a coma, dying and being pursued by a reaper, Bobby cooks up a plan to buy himself some time to wake up by trapping his reaper in his subconscious. Bobby and Rufus go about collecting the needed materials to summon the reaper, which includes: a crucifix, gold ore, hemlock, mace and blood, among other unknown ingredients. After painting a trapping sigil on the floor, the ingredients are set on fire as Bobby recites the phrase:

O theris tes, caleo se cai deo.

Which summons the reaper to his location and traps him.

Weaponized Spells

Kevin using the demon bomb.

Demon Bomb

The demon bomb is a powerful spell that is inscribed on the demon tablet for the defense of mankind, its effects are deadly to both demon and host. The spell was discovered by Kevin Tran, after being kidnapped by Crowley and forced to translate the newly discovered demon tablet. Three of the known ingredients needed for the demon bomb include: West Bank witch hazel, the skull of an Egyptian calf, the tail of a newt that according to Kevin, may or may not be extinct. Once properly mixed, the spell will release shock wave blasting and immolating any demons within it's radius, rendering the bodies nothing but scorch marks on a wall.

Due to the rare quality of ingredients, use of this spell is very difficult, as only demons or angels seem to be able to procure the needed materials.

The witch killing spell used against Spencer.

Witch Killing Spell

The first usage of the witch killing spell was in 7.05 Shut Up, Dr. Phil, Bobby supplies Sam and Dean, with a list of ingredients, of which the only known was chicken feet. Sam and Dean attempt to use the spell to put a stop to Don and Maggie Stark, once the Starks were in the same room the contents of the bowl were lite aflame as Sam recited the incantation:

Furor divina virtute in infernum eam detrude.

However due to the chicken feet being rotten, the spell was ineffective against the Starks.

A second variation of the spell was used in 8.15 Man's Best Friend with Benefits, like the prior spell it's exact contents are unknown other than chicken feet, however this version of the spell takes a liquid form. When James Frampton confronts the witch Spencer, and engages him in a fight Sam and Dean arrive and use the spell like a Molotov cocktail, Sam lights the rag in that is in the bottle while reciting an invocation in Latin:

Ego voco impetu delere,
vos caelum et infernum.

A smoke then envelops Spencer causing his body to disintegrate.

Binding Spells

The binding spell for Death.

Death

Death has been bound twice during the course of the series, first by Lucifer and then the Winchesters and Bobby Singer. The method for which Lucifer was able to bind Death is unknown, but it is assumed it was the same spell Sam, Dean and Bobby used. According to Crowley, binding Death requires a tremendous amount of power, and thus found the idea delusional. However he reluctantly agrees to hand over the spell to the Sam, Dean and Bobby.

The ritual itself required various common and easy to find materials, as well an act of God crystallized forever (Fulgurite). The ingredients must be mixed with blood in a bowl, which has been placed atop a special summoning sigil. An invocation in Latin must than be recited:

Te nunc invocomortem,
te in mea potestate defixi,
nunc et in aeternum!

Once done, Death will materialize and be bound to the will of the summoner(s).

Other Spells

Restoration Ritual

The dragons open a door to Purgatory.

Opening Purgatory

There appears to be three rituals to open the door to Purgatory, the first was performed by H.P. Lovecraft on March 10, 1937 at a dinner party. The specific ritual is unknown.

The second ritual was performed by dragons as means to bring Eve, the Mother of All Monsters to Earth. This ritual came from an ancient manuscript, it required a virgin sacrifice to serve an Earthly vessel for Eve, the blood of the summoner and an incantation in Latin:

Ego coniuro vos, insolubiliter ad mei potenciam aligati,
Ad me... sine prestolacione venire,
Debeatis aperiat,
Huc sine mora debeas mater!

Once the first line of the incantation is spoken, a doorway to Purgatory will open, at which point the blood of the summoner must bled into it, and the virgin sacrifice thrown into the portal.

Castiel stands at the door to Purgatory.

The third ritual was acquired by Castiel and Crowley through the torture of Eleanor Visyak. This ritual required a special sigil painted in the blood of a virgin and a native of Purgatory, the final part of the ritual requires a Latin incantation to be recited on the night of a lunar eclipse:

Ianua Magna Purgatorii
Clausa Est Ob Nos
Lumine Eius Ab Oculis
Nostris Retento

Sed Nunc Stamus Ad Limen Huius
Ianuae Magnae Et Demisse
Fideliter Perhonorifice
Paramus Aperire Eam

Creaturae Terrificae Quarum Ungulae
Et Dentes Nunquam Tetigerunt
Carnem Humanam Aperit Fauces
Eius Ad Mundum Nostrum Nunc
Ianua Magna
Aperta Tandem!

The angels being expelled from Heaven.

Angel Expulsion Spell

The angel expulsion spell, was a spell performed by Metatron to expel all the angels from Heaven. Metatron tricked Castiel into helping him gather the needed ingredients under the ruse of performing the trials from the angel tablet and locking Heaven down to try and bring peace to all the warring factions. The spell was so well hidden within the angel tablet that not even the prophet Kevin Tran was able to decipher it without translating it into a proto-Elamite cuneiform, which required Crowley's assistance in translating.

The spell required three specific ingredients that are tied to angels. The first ingredient was to kill and remove the heart of a Nephilim, the second ingredient required the bow of a Cupid, for which the cherub Gail gave up to Dean and Castiel without incident, the third and final ingredient was an angel's grace. According to Crowley's translation of the proto-Elamite cuneiform the next phase required Metatron to "mix until the smoke shall rise from the ashes casting the angels from Heaven," and that the spell was irreversible. Completion of the spell quickly caused all the angels to be ejected from Heaven, included the imprisoned ones. Many angels were killed in the fall, and left the others injured and weakened.
