Dayflower is edible and medicinal for colds and flu

The common dayflower looking like a three-eyed mouse is edible.

Mixing in with other plants in the garden is a clumping, grass-looking plant with alternating leaves clasping around the stem. Only after the blooms begin would one notice the common Asiatic dayflower weed (Commelina communis).

Looking like a cute, three-eyed little mouse, this Asian annual has two, iridescent cornflower-blue petals spread like ears, and a small, inconspicuous white petal underneath. Three yellow staminodes with dark-red centers look like eyes, while the lower stamen and style resemble the nose and whiskers.

Behind many of the mouse-flowers, are two, oval leaves closed as if in prayer, preparing to open on the following day to expose another little mouse.

Apparently, Carl Linnaeus, who came up with most of the botanical names for the plant world, inserted his notorious humor when he named the dayflower, Commelina, after three sons. Two of the sons had become famous botanists — represented by the two large petals, while the third son chose a less admirable path — represented by the inconspicuous white petal underneath.

Growing in disturbed areas in full sunlight, the common dayflower appears in most regions of the Eastern United States.

Some folks call it a troublesome weed, but if you eat it, or use it medicinally, it’s not so troublesome.

I think it’s rather sweet to have in the garden.

Leaves and shoots are edible with a green-bean flavor, and can be used in salads, or minimally cooked with other greens. The flowers, which bloom only for a day from May until October, are adorable additions to salads, or as a decorative accent to cupcakes.

The small seeds taste like peas and also are edible.

In China, the above-ground parts are used to cool fevers associated with the common cold and flu. A recent study on cells from dog kidneys and in live mice found that the common dayflower had a protective effect against the H1N1 influenza A virus.

Other medicinal uses for the dayflower are as a diuretic, eliminating excess fluids or as a gargle for sore throats.

Topically, the plant can be mashed and applied as a poultice to cool inflammation on the skin.

Dayflowers collect excess copper in the soil, which makes them useful for phytoremediation, a process of restoring the soil after contamination from industrial pollutants.

As an annual, the best way to keep this plant under control is to use it, preventing it going to seed, which you can easily do either by eating it or using it medicinally.

Elder offers a dose of preventative medicine

The elder tree is in an honored class of plants reaching a legendary, supernatural status. European folklore surrounds elder with stories of its powers, rumors of it being the tree from which Judas hanged himself, and warnings to anyone who treats it disrespectfully, as it is a protector from evil and home to the fairies.

Before harvesting any part of elder, the custom is to make an offering to the spirit of the plant. Reading of such superstitious hocus-pocus, skeptics will likely dismiss the plant, needing to experience its medicinal qualities to become true converts.

Early summer displays elder’s (Sambucus nigra, European, and Sambucus canadensis, North American) white, lacey, flat-topped blooms along roadsides. As the summer peaks, the flowers give way to sprays of pellet-sized purplish-black berries. Elder loves moist areas; I’ve found it growing along the pond at Oconee Forest Park in Athens, and in wet ditches along roadsides. According to Dr. Michael Dirr, elder will tolerate dry soils, but has an “unkempt habit” and easily naturalizes, giving elder a weed status in his book.

Traditionally, elder is considered a blood tonic among Europeans, American Indians and Appalachian people. Without knowledge of the mechanisms of the immune system, people theorized illness came from “bad blood”. Blood tonics, as a historical class of herbs, are excellent immune boosters and cancer fighters. Externally, elderflower water was popular among European women for removing freckles and sunburn.

As Civil War medicine, according to Confederate surgeon Dr. Francis Porcher (1863), elder leaves were heated in lard as a salve for wounds and sprains. Dr. Porcher also reports the berries make better spirits than the finest malt.

Current research reveals elderberry and flower’s antiviral efficacy on influenza, colds, sinusitis, and Herpes simplex and zoster. The flavonoids of elder contain immunostimulatory properties for influenza A and B. An in vitro study on H1N1 demonstrated how elderberry flavonoids would bind to and prevent H1N1 infection, by blocking the virus’ ability to infect host cells. Studies suggest elder’s immunostimulatory properties can be transferred to help with cancer and AIDS.

In cases of methicillin-resistant Staphylococcus aureus (MRSA), where therapeutic options are limited, elder is an alternative to antibiotics by preventing some of the mechanisms for Staphylococcus aureus to survive.

Elderflower’s flavonoids could be effective in the prevention and treatment of insulin resistance, stimulating insulin-dependent glucose uptake. The berries’ polyphenol antioxidants help lower the risk of metabolic diseases and cardiovascular illnesses.

The flowers and berries are edible. Berries make delicious jams and syrups, which kids love, and elderberry wine for the adults. When they’re ripe, though, I just like to add them to my yogurt, getting an ounce of preventative medicine for the day. Steep the flowers as a tea, or fry them as a fish-tasting fritter.

When harvesting elderflowers, lay the flower tops on plastic garbage bags for an hour or more to rid the flowers of resident insects. The bugs cannot tolerate fumes coming from the plastic. Berries don’t need the same treatment.

And please remember to respect your elder, making an offering of thanks to the elder tree spirits.
