Good day to all who read these thoughts on gardening and how gifts from nature can heal our bodies. It is in the upper 90s this week, and I am enjoying the weather immensely. It only happens a couple of weeks a year in Whitefish, MT, so hot weather is a pleasant reminder of what the southern states get much of the year.
Hot weather does alert me to the amount of humus in the soil and general fertility. It is a test for the plants to survive and keep producing above 90 degrees, and organic matter in the soil holds moisture for uptake by the roots of the plants. The reaction of the plants to these hot days (such as wilting) tells me which areas need more organic matter.
Of course, a good watering in the morning and evening helps plants cope with hot weather. In our area, the water is alkaline, so heavy watering makes the soil more alkaline. I use Yellowstone Sulfur pellets (which are organically approved) liberally in my soil to offset the alkalinity of both soil and water.
The Calendulas are still coming on strong. This year I planted a variety from Richter’s Herb Nursery in Goodwood, Ontario. It is Calypso Orange Calendula. It grows shorter than the Pacific Beauty I usually plant, and the flowers are consistently a deep orange, which provides more beta carotene for the extracts used in so many of our products. Calendula also carry a lot of resins at the base of the flowers that is medicinal, and my hands become sticky when harvesting them.
Here is some information about Calendula. They are very easy to grow, and reseed readily.
LOCAL HERBS AND HOW TO USE THEM - by Lynn Wallingford of Kettle Care ~ Pure Herbal Body Care

Also known as Pot Marigold, Calendula officinalis bears no resemblance to those golden annuals used for edging. It is available as an annual in local greenhouses and nurseries and is commonly used just because it is so pretty. Reaching up to 2 feet high, it is also an excellent cosmetic herb. It blooms from late May through September and is somewhat frost hardy. It reseeds readily, so let some of the flowers go to seed and look for the seedlings the next Spring. I like to use the Pacific Beauty variety. The seed is available as a flower seed, and as an herb seed.
Calendula (Calendula officinalis) in the daisy family (Asteraceae) is a small, cool weather annual with yellow or orange flowers. It is native to the Mediterranean countries and is also known as pot marigold. The name calendula comes from the Latin word for “first day of the month” and may refer to the fact that the plant can be found blooming at the beginning of most months of the year in the Mediterranean.
The German Commission E has approved calendula flower for both internal and topical use in treating inflammation of the mucous membranes of the mouth and throat. It is also approved externally for the healing of wounds; herbal infusions, tinctures, and ointments are used for skin and mucous membrane inflammations, such as leg ulcers, bruises, boils, and rashes. Antiviral and immunostimulating effects of calendula have also been reported. It reduces muscle spasms and tension, regulates menstration, is wound healing, styptic (stops bleeding through astringent action) antiseptic. Calendula has been shown to be effective for the prevention of acute dermatitis, especially during radiation therapy for breast cancer. Calendula is so gentle, it is suitable for people with sensitive skin, such as newborns and the elderly.
We grown hundreds of Calendulas in our cosmetic gardens at Kettle Care to use in a variety of products, including a Baby Creme (3C’s), Muscle Rub, Herbal Aid Creme, and Firefighters Creme.
Harvest Calendula flowers on a sunny day after the dew has dried (about 10 am to noon). This is when the essential oils are strongest in the flowers. The flowers easily pop off of the stems. Choose flowers that have recently opened. You will notice a resin on your hands after harvest.
Preparations:
Oil Infusion - Put Calendula flowers in a glass jar. Soak the flowers in enough vegetable or nut oil (olive is best) to cover. Seal it tightly. Set in a warm place for a week.
Alcohol Tincture - pour 1 cup of Everclear alcohol, 1 cup of distilled water over two ounces of freshly picked flowers. Seal it tightly in a clear glass container and let it stand for at least a week in the sun or in a warm place.
Water Infusion (Tea) – Boil one quart of water. Take off the heat; add ¼ oz. dried Calendula flowers. Let steep for 15 minutes; strain. Store excess in the refrigerator for up to one week.
Filter and it is ready for use. A cone coffee filter and filter paper work well for Tincture. Use a piece of flannel cloth for oil infusions. To store it, put the tincture or infusion in a sealed glass container and keep it out of direct sunlight. A dark glass container works best.
You can make a tea with Calendula flowers for menopausal problems, period pain, gastritis and throat inflammation. To use as a compress on slow healing wounds and varicose veins, apply a pad soaked in the tea, oil infusion or tincture. You can use your tincture or tea for mouth ulcers and gum disease.
You can also add various Essential Oils to the oil infusion, depending on your desired application. For sore muscles, joints and swellings, good Essential Oils are Rosemary, Lavender, Tea Tree, Cajeput and Thyme. Use 10 drops of Essential Oil to one ounce (two tablespoons) of oil infusion. In our products, look to muscle rub to provide you with relief using these herbs.
