I've never seen anything indicating that high dose vitamin D would be effective; however, I've never looked for anything like that, either.
The following comes from one of my blog posts and is reproduced in
Armageddon Pharmacy: Herbal Medicine When the Drugstore Is Closed, which came out on Amazon last month. The problem with a simple list is that it doesn't show how the herb must be prepared (and which supplies you had better have on hand) and administered, and which herbs may interact with medications you are already taking, or which must only be taken for short periods of time. Learning about herbal medicine isn't something to procrastinate.

Garlic is contraindicated for individuals taking warfarin or other anticoagulants or on HIV medications. Not a problem here, so the patient’s diet over the next few months of treatment will include lots of freshly prepared garlic. Teas or tinctures of gumweed, juniper, licorice, plantain, and/or sagebrush will be administered several times per day. As licorice shouldn’t be used long-term and is contraindicated in several groups of people, we’ll use it off and on in 10-day intervals. Peppermint essential oil will be inhaled several times per day. The numerous different preparations exist because some of the active constituents—the plant-based substances that are going to make you well—are extracted better with alcohol, or with water, or with heat, or are ruined by heat. The different applications function to get the medicine into direct contact with the afflicted tissue, whether through the bloodstream, on the skin, or through the organ that eliminates them—the liver, lungs, or kidneys. Some work fastest sublingually (under the tongue) and some work by direct contact with throat tissues."
