Herbs for Cold and Flu Season: Class Notes

Herbs For Cold And Flu Season: Class Notes

According to the US Center for Disease Control (CDC), flu and cold season typically covers October through May with its peak somewhere in December to February. In the Pacific Northwest, the rainy season’s damp and chilly weather provides the right conditions for viruses to thrive; for us, with the rain comes the flu and cold season.

Cold and Flu Prevention: The Best Solution

Lifestyle and Environmental habits can make a huge difference in how often you get sick and how long you stay sick. Basic Strategies for staying healthy include:

  • Eat a balanced, healthy diet, high in vegetables, low in dairy, carbohydrates, and meats.
  • Get plenty of rest.
  • De-stress and exercise regularly.
  • Practice good hygiene for yourself and your environment (Eucalyptus, Lavender, Tea Tree)

Add herbs that offer nutrition and immune-boosting energies to your diet, such as:

  • Nettle — High in Vitamins A, B, C; and essential minerals, calcium, iron, magnesium, potassium; Also contains beta-carotene, tannins, and a host of other nutrients. Pairs well with Raspberry Leaf. Nutritive, anti-histamine, mild laxative. Generally safe including during pregnancy and nursing, but can interact with some prescription drugs.

When Illness Happens: Ease the Symptoms

Even with the best prevention strategies, illness happens. Use these strategies to ease symptoms, prevent it from getting worse, and shorten the duration of illness:

  • Get rest (Valerian, Passion Flower, Hops, Oats)
  • Create a healthy atmosphere with aromatherapy (Eucalyptus, Thyme, Tea Tree, Lemon Balm)

Use herbs and foods to ease symptoms:

Recovery: Rebuild and Prevent Secondary Illnesses

Once symptoms begin to ease, it’s tempting to jump back into regular life. Don’t. Instead, give your body time and support in rebuilding your health. The best way to prevent relapses or secondary illnesses is through rest and healthful nutrition. Try these strategies:

  • Make time and space for proper sleep.
  • Ask for help in catching up on tasks that slid while you were ill.
  • Ease back into life, and support your system with foods and herbs that support good health, including all of the prevention herbs plus gentle detox herbs like Dandelion, Burdock, Cleavers, Red Clover, and Licorice Root.

Daily Illness Prevention Recipe: Fire Cider Tonic Vinegar

Fire Cider tonics are an excellent, easy way to build daily illness prevention into your life. Try a classic recipe, such as Rosemary Gladstar’s Fire Cider, or a Pacific Northwestern take on the Fire Cider mix such as Sue Sierralupé’s Fire Salamander Cider Recipe on The Practical Herbalist. Take a tablespoon or two daily directly or watered down, or incorporate a couple of tablespoons into your daily diet. These tonic vinegars make a lovely salad dressing or flavoring for greens or other cooked or roasted vegetables. They’re also dynamite at helping your body create the kind of environment that’s less hospitable to viruses and bacteria, making them a good medicine when you’re ill as well.
