~Introduction and The Stirring Charm

-Boil: Infection located in a gland or hair follicle
-May appear like inflamed/painful pimples
-Infections can spread
-Muggles usually soak boils in hot water for days, drain the boil, then clean/dress it
-The Cure for Boils works more quickly than Muggle solutions
-Potion applied topically, drawing boil to a head
-Boil then pops and drains
-Be sure to clean the drained site with dittany or other healing potion/herb
-Kelvin measures thermodynamic temperature
-Named after William Thompson, aka First Baron Kelvin.
-Wrote a paper in 1848 that called upon the need for an absolute thermometric scale.
-Wear goggles at all times and Ephesial’s Eye-Saving Rinse is kept on hand
-The Stirring Charm
Incantation: Halato((hah-LAH-toh)
Wand Movement: Smooth, even circles either clockwise or counterclockwise

~The Cure for Boils
-EBT:
Pewter cauldron: 45 minutes
Brass cauldron: 39 minutes
Copper cauldron: 33 minutes
-Ingredients:
750 ml of water
6 snake fangs
4 horned slugs
2 porcupine quills
3 measures Flobberworm mucus
-Instructions(Please note that the following is copied straight from lesson):
(part 1)
1. Add 750 ml of water to your cauldron and bring the temperature to 363 Kelvin (90°C/194°F).
2. Add all six snake fangs to your mortar and crush them into a fine and even consistency using your pestle.
3. Take the tablespoon you see beside your mortar and add four measures of the fangs to your cauldron.
4. Heat your cauldron to 383 Kelvin (110°C/230°F) for ten seconds, then turn down the flame to 363 Kelvin (90°C/194°F). Don't ignite anything while adjusting temperature
5. Wave your wand once clockwise. At this point your potion should have a pink hue.
6. Depending on your cauldron, your brew times will vary. For the purpose of today’s lesson, you can leave your pewter cauldron brewing for 22 minutes. Throughout much of this potions’ brewing, you will notice that, even as the color of the potion changes, the smoke remains pinkish in hue. (If you were using a brass cauldron, the brew time would be approximately 19 minutes. Copper cauldrons have a brew time of 16 minutes during this step.)

(Part Two)

1. At this point, all four horned slugs should be added directly to the cauldron.
2. It is important during this step to take your cauldron completely off the flame before adding your porcupine quills. Failure to do so will result in the potion emitting a terrible odor and your cauldron melting. When this happens, the compound is known to cause very painful boils.
3. Now that your cauldron is off the flame, add two porcupine quills to the potion and then return it to the heat.
4. Wave your wand five times clockwise and ensure that the heat is still at 363 Kelvin (90°C/194°F).
5. Let the Potion finish brewing for 17 minutes (This would be 15 minutes for a brass cauldron or 12 minutes for copper).

(To Finish)

1. At this point, take your cauldron off the flame entirely. The potion should be sky blue in color, and the potion will begin to stop steaming as it cools down.
2. Add Flobberworm mucus (about three measures), and leave to thicken for about five minutes.
3. Stir the potion to ensure it is of a uniform consistency, and then use a funnel to bottle it in a clear glass or crystal phial. Remember to correctly label your phial before storing it.

-Usage Notes: Don't use on sensitive areas of skin(Ex: face, eyes)
-If potion gets in eyes, flush them out
-Potion is safe for all ages
-ONLY apply topically - do not eat!

~Storage of Potions

-Label every phial clearly
-Take into account amount of light
-For potions requiring darkness, use a tinted glass or crystal phial

-Cure For Boils can be stored at room temp. for up to 4 years
-Ministry has hazardous potion collections biweekly
