Edible & Medicinal Flowers

No Comments

We value beauty for its own sake, yet many colorful flowers have much to offer beyond their good looks. Some can be used medicinally, others are good to eat, and many provide food and habitat for beneficial insects. These common plants and simple wildflowers can make a colourful addition to your garden design and you can take advantage of their medicinal and culinary characteristics.

As the weather warms up suburban gardens come into full bloom – and some of those flowers not only look beautiful but taste great as well. Chives, borage, broccolini, oxalis, nastertium and pineapple sage all have flowers you can use on the plate as well as in a vase.

Cautions For Eating Edible Flowers

Not all plants and flowers are edible, but there are many that are. First, you should only eat flowers or the parts of the flowers that can be properly identified as actually edible. Many plants can be confused, and this can prove to be fatal. When in doubt, don’t eat it.

Next, you must be careful when selecting flowers to eat or use in food. Do not eat flowers from a garden center, as those are most often treated with pesticides or fertilizers. This can cause sickness when consumed.

You should also avoid flowers and plants growing on the side of the road. These plants absorb run off from vehicles and chemicals from the asphalt and tar.

Grow edible flowers for salads, teas, cakes, and more in your own garden. There you can control how they are grown. They also won’t be mixed up with other, potentially dangerous flowers.

Best Edible Flowers To Grow

We’ve used flowers for health and food for centuries. It’s a testament to their plentiful benefits. While plants and flowers have evolved over time, they still offer many benefits today. Take a look at these nine healthy flowers and consider growing edible flowers in your own garden.

Edible Hibiscus (Hibiscus rosa-sinensis) or (Hibiscus Sabdariffa)

Hibiscus is one of the most commonly used edible flowers and is found in drinks, teas, relish, jam, syrups, and kombucha. It may also be used as a garnish in salads, entrees, cakes, and so much more.

Edible tropical flowers like hibiscus are found in a wide range of colors, including red, white, yellow, and several shades of pink. You can eat the blooms straight from the plant if it is grown without pesticides. The flavour is quite sweet as well as tart, almost like cranberry, which is why it is most often used for teas.

Mostly they have cranberry-like flavour with citrus overtones.  Use slightly acidic petals sparingly in salads or as garnish.  The flower can be dried to make an exotic tea.

Most popular edible variety of hibiscus: Roselle (Hibiscus Sabdariffa)

Health benefits: reduces blood pressure and cholesterol, and supports heart health.

Edible Dandelion (Taraxacum officinale)

Dandelions may be a stubborn garden weed, but they are highly nutritious. Packed with antioxidants, you can eat these bright yellow flowers in their entirety: leaves stems, roots, and flower heads.

Flowers are sweetest when picked young.  They have a sweet, honey-like flavor.  Mature flowers are bitter.  Dandelion buds are tastier than the flowers: best to pick these when they are very close to the ground, tightly bunched in the center, and about the size of a small gumball.  Good raw or steamed.  Also made into wine.  Young leaves taste good steamed, or tossed in salads.  When serving a rice dish use dandelion petals like confetti over the rice.

Common options include eating them raw, adding them to salads, or brewing them into a tea. Modern cooks have also come up with other, more interesting methods.

Other Ways to eat dandelions: as dandelion wine, syrup, cordial, raw, in a stew or casserole, in salad, tea, or jelly. You can also bread and fry them, though this is more likely to be seen in a fancy restaurant than at home.

Health benefits of dandelions: a good source of antioxidants, dandelions reduce cholesterol, regulate blood sugar, reduce blood pressure and inflammation, boost your immune system, reduce risk of cancer, and aid digestion and skin complexion.

Edible Lavender (Lavandula angustifolia)

Most people enjoy lavender’s scent and calming qualities. It’s often used for beauty products, baby skincare products, as a fragrance in perfumes, and as a sleep aid in teas. However, the use of lavender doesn’t stop there.

Lavender’s sweet aroma pairs nicely with citrus fruits, chocolate, rosemary, sage, and thyme. The flower is often added to baked goods, either as a flower garnish or flavoring. Infused syrups, liqueurs, teas, and spice rubs are also made with lavender.

Health benefits of lavender: good source of vitamin A, gentle sleep aid, stress relief, aids the digestive system.

Edible Pansies (Viola X wittrockiana)

Pansies aren’t often considered on lists of edible flowers, but they really should be. Not only are they beautiful to add dishes (especially since they come in many colors), they are also very tasty. Their flavor is very mild, though it does vary based on the type of pansy. Some varieties have a very earthy, or even minty flavor, while other Pansies have a slightly sweet green or grassy flavour.  If you eat only the petals, the flavor is extremely mild, but if you eat the whole flower, there is a winter, green overtone.  Use them as garnishes, in fruit salads, green salad, desserts or in soups.

They’re a great addition to fruit salads, summer cocktails, savory snacks, or sugary treats. If you coat them in egg whites and sugar, they have the potential to keep for several months.

Pansies edible flowers also used for: pastries, cakes, cookies, as a garnish, in salad, on cheese logs.

Health benefits of pansies: rich source of antioxidants, reduce inflammation, high source of vitamin C, relief for eczema, hives, and itching, asthma, bronchitis, whooping cough, and congestion. Also eliminate certain bladder infections, to treat epilepsy, and alleviate symptoms of arthritis and rheumatism.

Edible Chamomile (Matricaria chamomilla)

pasted image 0 2Chamomile is often used in teas, mostly for its calming abilities. It’s great for easing anxiety or aiding sleep. These delicate, daisy-like flowers, with their earthy, sweet flavor, have many benefits. But they’re not as easy to cook with as other edible plants. First, you should boil the flowers in a liquid to make syrups or extracts for use in baked goods and smoothies.

Health benefits of chamomile: ease your digestive system and stress, and aid sleep. Also a good source of vitamin A. It is also said to reduce menstrual pain, treat diabetes and lower blood sugar, slow or prevent osteoporosis, reduce inflammation, treat and prevent cancer, treat colds and aid with skin conditions.

Edible Calendula (Calendula officinalis)

Calendula, also known as the “poor man’s saffron” or pot marigold, has the taste of saffron when sauteed in olive oil. This spicy flower is great for deviled eggs, salads, breads, herbed butters, cheese spreads, and soups. It’s easy to grow from seed in your garden, and will bloom from early summer to late fall. Flavors range from spicy to bitter, tangy to peppery.  Their sharp taste resembles saffron (also known as Poor Mans Saffron).  Has pretty petals in golden-orange hues.  Sprinkle them on soups, pasta or rice dishes, herb butters, and salads.  Petals add a yellow tint to soups, spreads, and scrambled eggs.  Only the petals are edible.

Cautions when consuming calendula: Don’t consume calendula if pregnant. It may cause extreme drowsiness if taken with allergy medications.

Health benefits of calendula: full of antioxidants and vitamin A, can keep your skin healthy and your eyes functioning properly. A salve made from the flowers is commonly used to help heal minor skin irritations and abrasions.

Edible Roses (Rosa rugosa or R. gallica officinalis)

Like pansies, eating roses isn’t a very common thing. Yet throughout time, people have eaten roses, They’re also added to baths and fountains for freshening up. Their flavor is rather fruity, like strawberries and green apples. This makes them great in teas, jams, salads, and desserts.

Some people freeze them in ice cubes to add to lemonades, sangrias, and punches. They’re also an elegant garnish on ice cream or desserts. No matter how you eat them, they are a great and healthy addition to your diet.  All roses are edible, with the flavor being more pronounced in the darker varieties.  In miniature varieties can garnish ice cream and desserts, or larger petals can be sprinkled on desserts or salads.  Petals used in syrups, jellies, perfumed butters and sweet spreads.  NOTE: Be sure to remove the bitter white portion of the petals.

Health benefits of eating roses: contains vitamin A and E, treats digestive issues and menstrual disorders, calming for skin and can reduce inflammation.

Edible Sage Flowers (Salvia officinalis)

Sage flowers are unique in that they taste of both sweet and savory flavors. Because of this, they pair well with lemon and other garden herbs. They are often used to make herbed vinegar, tea, or floral food decorations. There are many varieties of sage, but the most common one used is garden sage. While most people avoid the flowers, they are just as beneficial as the rest of the plant.

Also, Pineapple Sage does well in containers and blooms for most of the summer. It’s a good one for attracting hummingbirds. Harvest the leaves. You can dry them and use as an herbal rub on fish. Drop a few leaves into a glass of iced tea, as you would a mint leaf, for a fragrant pineapple accent. Unrelated to pineapple, pineapple sage gets its name from the flower’s sweet smell. Its mild sage flavour goes well with fruit so the flowers make a fantastic addition to fruit salads or banana smoothies. The leaves can also be used.

Health benefits of Sage Flowers: may help promote brain health, including strengthening memory. Also a source of vitamin B, calcium, manganese, vitamin K, Iron, and more. Sage may also help with oral issues, ease menopause symptoms, reduce blood sugar levels, lower bad cholesterol, and help prevent cancer.

Edible Mint Flowers (Mentha spicata)

pasted image 0 1Most people don’t know that mint grows flowers, but many varieties of mint do. All flowers in the mint family are edible. As a matter of fact, sage also belongs to the mint family. Most people use them for teas, but you may also see mint flowers used in custards, salads, fruit salads, spring rolls, yogurt, and desserts.

Are All Types of Mint Plants Edible? No, not every type of mint is safe to eat. Some are grown as trees or shrubs, while others are purely decorative. The best way to tell if it’s edible is by seeing how it smells. If it has a square stem and smells like mint, then it’s mint, which is edible. If it smells of mint and has a Labiate flower (usually in clusters around and close to the stem) then you are pretty safe. But rule of thumb in mycology or botany, if in doubt don’t eat it.

Health benefits of mint: a good source of vitamin A, iron, manganese, and folate. Great for eye health, and a potent source of antioxidants. It may also provide relief for irritable bowel syndrome, improve brain function, and decrease breastfeeding pain.

IMPORTANT – Some dos and don’ts!

Following are some simple guidelines to keep in mind before you eat any type of flower:

DO’S:

Eat flowers only when you are positive they are edible.  If uncertain, consult a good reference book on edible flowers prior to consumption.

If pesticides are necessary, use only those products labeled for use on edible crops.  No flowers is safe to eat unless it was grown organically.

Wash all flowers thoroughly before you eat them.

Introduce flowers into your diet in small quantities one species at a time.  Too much of a good thing may cause problems for your digestive system.

Remove pistils and stamens from flowers before eating.  Separate the flower petals from the rest of the flower just prior to use to keep wilting to a minimum.

Eat only the flower petals for most flowers except pansies violas, and Johnny-jump-ups (in which they add flavor).

If you have allergies, introduce edible flowers gradually, as they may aggravate some allergies.

DON’TS:

Do not eat flowers from florists, nurseries or garden centers.  In many cases these flowers have been treated with pesticides not labeled for food crops.

Do not eat flowers picked from the side of the road.  Once again, possible herbicide use eliminates these flowers as a possibility for use.

Just because flowers are served with food served at a restaurant does not mean they are edible.  Know your edible flowers – as some chefs do not.  It’s easy and very attractive to use flowers for garnish on plates or for decoration, but avoid using non-edible flowers this way.  Many people believe that anything on the plate can be eaten.  They may not know if the flower is edible or not and may be afraid to ask.

Recovering Anosmia for people experiencing loss of smell after Covid-19

The Spread of the Virus

Late December 2019, an outbreak of a mysterious virus characterized by fever, dry cough, and fatigue, and occasional gastrointestinal symptoms happened in a seafood wholesale wet market, the Huanan Seafood Wholesale Market, in Wuhan, Hubei, China.1 And before we knew what was happening we were in the middle of a terrible worldwide pandemic that caused massive shut downs and quarantine that has shaken everyone in many different ways.  Many of us have lost loved ones and friends to the virus, suicide and loneliness from being isolated and in quarantine. Many people lost their jobs, homes and every sense of normalcy.  For me, my best friend for over 50 years, Toni, came down with the virus and was hospitalized.  Luckily, she is recovering, however Toni no longer have a sense of smell nearly six months later.

Psychology and Smell

Smell is an important sense as it can alert us to danger like gas leak, fire or rotten food but also is closely linked to parts of the brain that process emotion and memory. Smell is vital for survival of most humans and animals as it enables them to track food and water, find a mate and even communicate. When you lose your sense of smell you can also lose some important memories that are triggered by aroma. Given that our sense of smell clearly plays an important part in our psychological make-up, in addition to it being one of the five ways in which we connect with the world around us, its absence can have a profound impact. Many people feel isolated and can lead to depression.11

I consider myself a wine enthusiast and have obtained a WSET Certificate with distinction in blind tastings.  Through this study I have found our sense of smell has a profound affect on the way our brain processes flavor.  Once you smell something the flavor is much stronger. This is why smell is so important when it comes to tasting a wine.  It is also the way that you can describe a wine. Common aromas associated with wines include fruit, herbs, flowers, earth, grass, tobacco, mocha and chocolate. So in order to be proficient in identifying the aromas, I had to do a lot of “smell training” from little bottles of aromas and then identify these smells in the wine.  It is from this training that I decided I’d love to learn more about aromatherapy.

Loss of Smell

Early in the COVID-19 pandemic, it emerged that many people infected with the SARS-CoV-2 virus were losing their sense of smell — even without displaying other symptoms. Almost a year later, some still haven’t recovered these senses, and for a proportion of people who have, odours are now warped: unpleasant scents have taken the place of normally delightful ones.  Through my research I found one review, published last June3, compiled data from 8,438 people with COVID-19, and found that 41% had reported experiencing smell loss. In another study, published in August4, a team led by researcher Shima T. Moein at the Institute for Research in Fundamental Sciences in Tehran, Iran, administered a smell-identification test to 100 people with COVID-19 in which the patients sniffed odors and identified them on a multiple-choice basis. Ninety-six per cent of the participants had some olfactory friend is in the 18% with total loss of smell. So, since I have been studying aromatherapy, I started researching the possibility of essential oils and their ability to help her regain this very important function.  Firstly, I had to know the scientific reasons for the loss of smell.  Were the cells in the nose damaged or was it a neurological issue, something in the brain?

Why, why, why

Although the mechanisms are not fully understood, A team led by Sandeep Robert Datta, a neurobiologist at Harvard Medical School in Boston, Massachusetts, has instead found5 that cells that support sensory neurons in the nose — known as sustentacular cells — are probably what the virus is infecting. The study suggests that the coronavirus infects the support cells, leaving the neurons vulnerable and deprived of nutrients.  But there are many other conflicting studies.  And no one really knows for certain why people who have had Covid 19 are losing their sense of smell.  It’s just too early in the studies to have a definitive answer.

Claire Hopkins, an ear, nose and throat consultant at Guy’s and St Thomas’ Hospital in London, and her colleagues similarly observed6 as a person regains their sense of smell, odours often register as unpleasant and different from how they remembered them, a phenomenon called parosmia. “Everything smells rancid” to these people, says Hopkins, and the effect can last for months. This might be because the olfactory sensory neurons are rewiring as they recover, she says. Other patients remain fully anosmic for months, and it isn’t clear why. Hopkins suggests that, in these cases, the coronavirus infection might have killed the olfactory sensory neurons.  Which left me wondering what is the possibility of regaining the sense of smell.  Is it that the neurons simply had to remember how to smell or were they killed?  Since I had no way of knowing I decided to try to retrain Toni’s sense of smell to relearn them.  I found that I was not alone in my thinking.

Smell Training

A charity called AbScent in Andover, UK, has been offering a program to retrain the sense of smell. There is evidence7 from before the pandemic that it can improve smell function in some people with such impairments, but it doesn’t seem to work for everyone.  So I visited their website (https://abscent.org/learn-us/smell-training) and found “If you’ve lost your sense of smell for two weeks or more, smell training can help recovery. Smell training is actively sniffing the same four scents every day, spending around 20 seconds on each scent and really concentrating on what you’re doing. It’s that easy. It’s safe, it’s recommended by doctors, and anyone can do it.”

With this in mind, I knew I was not doing anything ground breaking, but decided to go along with this theory of regular stimulation of their olfactory “brain” and prepare smell training for Toni with the intension of helping her recover hermsense of smell.

Case Study in Smell Training

Following the guidelines in the AbScent smell training website, I did a complete assessment of what she could smell taking notes so that we can measure any improvements. You can find the assessment here: https://abscent.org/application/files/5515/7532/6861/Self_assessment.pdf.

Instead of using jars as they used for the Abscent study, I put together these inhalers (below) for Toni which was inspired from the original Abscent 2009 study.  My information in reference to the oils used is from the Data Sheets is from Aromahead Aromatherapy Certification Course and also from Aromatics International website where I purchased the oils.

  • Lemon Essential Oil (Citrus limonum) is cold pressed from the lemon peel and it is known to flight exhaustion and is also very uplifting. This is because the olfactory gland in our sinuses helps turn smells into chemical responses for our brain to process. Toni is still struggling from exhaustion while recovering from the virus so I am sure this will benefit her in an emotional way as well as the smell training.
  • Rose Absolute Oil (Rosa x centifolia) is an anti-depressant, calmative and also just smells great and I know Toni loves Roses. For a long time, I thought all oils were basically created equally. While that may be the case for true essential oils, some organic material cannot be subjected to the same processes that are used to create essential oil. It’s important to note that essential oil is created through a method known as steam distillation, wherein heat (steam) is used to extract the various vitamins and minerals from the organic matter through evaporation. However, certain types of organic material are too sensitive for steam distillation and cannot withstand these high levels of heat. Because of this, a process involving the use of various chemical solvents is sometimes used to extract the phytochemicals, vitamins, nutrients, and other bioactive compounds from organic matter. The end result of this process is known as an ‘absolute’ and it’s important for me to stress that it is not an essential oil.
  • Clove Bud Essential Oil (Syzygium aromaticum) is steam distilled from the flowering buds of the clove tree and is great for easing respiratory conditions. I also find it invigorating and mentally stimulating.  Clove Bud Oil (rather than leaf which is distilled from the leaf) is a much stronger scent and is usually used in aromatherapy. Clove Bud Essential Oil generally contains up to 85% Eugenol, a phenol that dramatically contributes to the oil’s aroma, therapeutic properties, and safety precautions (which can be irritating to the skin). Clove Bud Essential Oil is also comprised of a number of other constituents, particularly the sesquiterpene B-caryophyllene and the ester Eugenyl acetate. American College of Healthcare Sciences principal Dorene Petersen has undertaken research regarding cognitive and brain health. She presents that Clove Bud Essential Oil shows promise for assisting in the management of neurodegenerative diseases.9   So now I understand that this oil may also assist in the memory of the smells and is an excellent choice for this smell training case study.
  • EucalyptusEssential Oil (Eucalyptus citriodora) is distilled from the leaf of the tree and is used for its soothing effects when inhaled, for example during a cold or cough and is an immune-boosting oil.  Which is also perfect for the inhaler for smell training after a virus.  Eucalyptus should not be used on children as it can irritate their respiratory track and if not used correctly can cause poisoning. The main constituents of Eucalyptus Oil are: α-Terpineol, 1,8-cineole (Eucalyptol), α-pinene, β-pinene, Sabinene, Camphene, Limonene, p-Cymene, Camphor, Globulol, Citronellal, α-phellandrene, Aromadendrene, and Piperitone.

 

Guidelines and Instructions for Smell Training

I packaged up the inhalers and typed up some instructions for use which included:

  • Keep the inhalers beside your bed so that you can use them when you wake and before you go to sleep.
  • Take a short breath and gently inhale the lemon scent (for instance) for about 20 seconds. (There is a snif app that will help time you and also offer visuals. This is located on the Absent website as mentioned previously and is in the bibliography.)
  • Block out any intrusive thoughts.
  • Try to remember everything you know about lemons both smell and tasting.
  • Next move on to the next inhaler and repeat this process.
  • Continue doing this twice a day for four months. It is not a quick process but the earlier you start the quicker the process.

Remember to Record your progress in a journal. Your smell training results may be better or worse on any given day so it is best to record your progress every 3 weeks. Download this handy diary or try AbScent’s Snif App to help with the routine of smell training and record your results on your mobile device or desktop.E

Conclusion

While the study is ongoing, we have seen some promising results. Nerves take time to heal.  Depending on the damage, this could be two months or it could be two years or even longer.  No one can predict how long recovery will take or how completely anyone will recover.  But we do have evidence that smell training helps 10 .  These studies have shown that smell training may help recover smell performance (identifying and distinguishing smells) caused by parosmia in patients with smell loss caused by a viral infection. Although speculative, these findings stress the importance for future efforts in experimental and clinical research regarding olfactory neuron regeneration in different types of olfactory loss.  I will keep you updated on the results from my case study with which is still in the early stages and hopefully will have a positive conclusion.

Aromatherapy is an amazing recourse, with the ability to stimulate cognition and memory, enhance mood, and curb cravings. Of course, smells are indisputably a very strong link to the past. The benefits of aromatherapy are the proof of the efficiency of our sense of smell in the present; therefore, if olfaction is a window into the past as well as a supportive and healing tool in the present, with this knowledge how can we change our future?   I leave you with an important quote: “Knowledge without application is simply knowledge. Applying the knowledge to one’s life is wisdom — and that is the ultimate virtue.” ― Author Kasi Kaye Iliopoulos.
