Aiding the Wharf

We have read the tides, and never before have I seen them in such turmoil. They call to the tidesages, begging for help. A debilitating sickness is running rampant amongst the villagers, and it comes from the sea. We are but few. There is only so much we can do! Please, take this list and gather the listed reagents from around the pier while I attempt to calm these folks. I should be able to create a tonic that will help. I hope.
