3 Must Have Medicinal Plants: how to grow and use

Easy to grow and use medicinal plants for common ailments.   

Why grow your own medicinal plants instead of buying ready made herbal supplements ?

I like to grow my own medicinal plants in order to ensure authenticity of healing herbs, have a fresh supply of medicinal plants on hand when needed, and just because I love to have a connection with the things that nourish my body. smile

But still – the main reason for me is concern about the authenticity of a product.

When I moved to the U.S.A. and decided to buy herbs in bulk from a local health store – dried German chamomile flowers and linden flowers – I  was sold wrong products, and it was something that I was able to see and clearly identify unlike a supplement in the pill form or crushed herbal tea in the package.

You see, because herbal remedies are not regulated by FDA (Food and Drug Administration), when we are buying prepared and packaged medicinal teas and herbal supplements there is no way to know that  what is written on the label is indeed the herb that we are getting. When buying a supplement, we just rely on the honesty of the company producing it.

But should we be so trusty?

According to a CBS news report about the results of an investigation led by New York Attorney General Eric Schneiderman, only 21 percent of the herbal supplements from four major retailers: GNC, Target, Walmart and Walgreen actually had DNA from the plants advertised on the labels. When looking at Walmart numbers alone – it is even scarier: only 4 percent of the products tested showed DNA from the plants listed on the labels.

Useful Tip

When you are buying herbal supplements, to insure the potency of major active ingredients of medicinal plant always look for words “standardized extract” on the label.

A good thing is that you can grow your own medicinal plants in your garden or in pots on your patio. Some of them are very easy to grow and help with a lot of common ailments.

Is herbal medicine safe?

A word of caution before we proceed: herbal medicine is not risk free. Herbs have medication like effects: they can heal and harm, especially in large or repeated doses. They also can interact with prescription medications. It is recommended to consult your doctor before taking herbal supplements, especially if you take medications, are pregnant or breastfeeding, or have chronic health problems.

Before using any herb you should be able to identify it correctly. I, personally, would stay away from herbs grown in the wild, because there are a lot of look alike plants that can be harmful.  And, as with everything else in life, when dealing with herbs – use common sense.

Useful Tip

Before using herbs, investigate potential benefits and side effects of medicinal plant or herbal supplement  A good place that will provide you with research based information is National Center for Complementary and Integrative Health  and the Office of Dietary Supplements of National Institutes of Health.

Why I chose these 3 medicinal plants?

My friend knows – I love my medicinal herbs, can not do without them! So, one day we were talking and she asked me, “What if you were allowed to plant  just 3 medicinal plants, which ones would you choose?” I told her, that it is impossible, I need to have at least 10 to cover all common ailments. “No”, she insisted. “You should pick no more than 3, because the lack of space, or time, or any other constraint, it’s your challenge!”

OK, I love challenges…wink

So, I thought for a while for plant choice criteria and decided that I would want plants that

  • are easy to grow. Plant once and have supply forever
  • have long growing season, so fresh material for natural remedies is available as long as possible during the year
  • used by me most frequently
  • can help with the most common ailments (combined between 3 of them)
  • act upon the body in the most safe and gentle way with no side effects reported

Considering my criteria I came up with 3 winners:

Korean mint – helps with ailments inside the body.

Calendula – first aid for wounds and cuts, used for everything on the surface of the body as well as inside the mouth and throat.

Lemon balm – aids with mental well being by reducing stress and relieving anxiety.

All 3 plant also exhibit antibacterial, antimicrobial, and antiviral properties. All are great antioxidants, and are suitable for more than just medicinal uses.

They are all easy to grow. Korean mint and lemon balm are perennials. Calendula, though annual, will grow year after year if you give it a dedicated patch in the garden or container and allow it to reseed naturally.

I am aware that you might have different needs. You can create your own criteria for the choice of medicinal plants and pick the ones that suit your needs. You can start small – with just 3 plants, and expand your healing herb garden with time.

 

1. Korean Mint (Latin name – Agastache rugosa)

This is my favorite medicinal plant for stomachache or any digestive problems.

How to grow Korean mint

Korean mint, also known as purple giant hyssop, huo xiang, or blue licorice, is a hardy prolific perennial that is deer and rabbit resistant. Be aware that Korean mint can become invasive.

It can grow almost in any soil, and is happy when planted in a container on your patio or balcony. It overwinters just fine in open soil or in the pot when left outdoors in zones 4 – 9.

Korean mint can grow to 3-4 feet tall, likes sun, but will take a partial shade.

It blooms profusely by producing  spikes with pretty lavender flowers from June till mid-autumn and attracts lots of bees.

Korean mint will grow from seeds, plant division, or from cuttings.

The seeds need light to germinate – so the best it just to scatter them on the top of the soil, tightly press into the soil with your palm , and water with warm water. 

You can start to grow seedlings indoors in late February and replant them outdoors after the danger of last frost passes, or sow seeds in open soil after danger of frost passes. 

After you grow your first Korean mint plant and let it to reseed itself – you will have an endless supply of healing leaves for years to come.

How to use Korean mint

The leaves of Korean mint are edible and some people use them in salads, but the leaves have coarse texture and too strong smell as to my liking, so I do not use them for culinary purposes. When a leaf id crushed – it smells like licorice and mint combined. It odorizes the house with fresh scent. In Korea the leaves are used in fish stews.

The easiest way to use Korean mint for medicinal purposes, is to make a tea from fresh or dried leaves.

Korean mint tea recipe

  1. Place around 2 tablespoons of chopped fresh Korean mint leaves ( or 1 tablespoon of crushed dried leaves)  in a cup.
  2. Pour 1 cup of boiling water over the leaves. Cover the cup.
  3. Let it steep for 10 minutes.
  4. Strain.

You can enjoy this tea once a day just for a pleasant drink. For medicinal purposes it is recommended to drink half cup of this tea  3 times per day 20 minutes before meals.

2. Calendula (Latin name – Calendula Officinalis)

First aid remedy for cuts and wounds anywhere  on the skin or in the mouth.

Calendula – is one of the easiest plants to grow. It loves full sun, but will grow in partial shade in the garden or container. You can sow it in open ground after the danger of frost passed or start seeds indoors and replant seedlings in open ground in late April. When your plants get established, you can collect your own seeds in the autumn and plant them the next year. Alternatively, you can let plants reseed themself. Though calendula is an annual, by giving it a dedicated place in your garden or container on your deck, and letting seeds fall on the ground – calendula will take care of its own growing and will greet you next year with cheery yellow-orange flowers.

Calendula Medicinal Properties

I have another article dedicated to calendula medicinal properties where I describe them in great detail, so I will just quickly recap here what calendula can treat due to its antiviral,  antibacterial, antifungal, anti-inflammatory, antioxidant, antigenotoxic, hepatoprotective, and wound healing properties.

Calendula if used topically is:

  • first aid remedy for wounds, cuts, scrapes, swelling, inflammation on the skin and inside the mouth
  • applied to the skin to reduce pain and swelling (inflammation) and to treat poorly healing wounds and leg ulcers, nosebleeds, varicose veins, hemorrhoids, ear infection, yeast infection, gum disease, peeling lips, diaper rash, and conjunctivitis.
  • treats acne
  • gargle for sore throat
  • insect repellent

Calendula is used internally for:

  • menstrual cramps, stomach  ulcers, measles, smallpox, and jaundice
  • effective against flu and herpes viruses, helps body to fight pathogens
  • removes toxins from lymph system, reduces lymphatic congestion and infection

How to use calendula

For medicinal purposes fresh or dried calendula flowers are used. If you are going to dry your own flowers – early summer is the best time to pick them to ensure their peak healing properties.

Useful Tip

You can prepare natural remedies at home by extracting beneficial components from calendula flowers, using different kinds of media:

  • alcohol – to make calendula tincture
  • oil – for calendula infused oil

3. Lemon balm (Latin name – Melissa Officinalis)

medicinal plant to reduce stress and anxiety and to improve your mood

Lemon balm (Melissa officinalis)

How to grow lemon balm

Lemon balm is a cold hardy and easy to grow perennial that can survive 20° F. It grows well in open soil and in pots. Lemon balm prefers full sun and moist soil. If you let it self-seed – the plant can become invasive.

In its growing habits melissa is very much like Korean mint. You can grow melissa from seeds sown in open ground in spring, or start seedlings indoors in late winter and replant them in spring. Well established plants can be divided.

To harvest lemon balm for medicinal tea, simply take clippings as needed from your plants or pluck individual young leaves.  The newest growth is the most flavorful.

You can dry melissa using different methods: shade drying, sun drying, and oven drying  at  100° F (40° C)

Useful Tip

The research shows that “fresh lemon balm herb had the highest essential oil content followed by shade drying, oven drying and sun drying respectively…  Drying methods had no effect on the number of chemical components of the essential oil, as 43 components were identified in the essential oil of each drying method. ” 

Lemon balm medicinal properties

Called by Paracelsus “the elixir of life”, lemon balm (Melissa Officinalis) has been known for  centuries for its calming properties. Its leaves have strong lemon scent. It is interesting to note, that a  scientific experiment conducted to study olfactory influences on mood  “provided robust evidence that lemon oil reliably enhances positive mood compared to water and lavender regardless of expectancies or previous use of aromatherapy.”

According to recent research, lemon balm exhibits anitimicrobial activity (antiparasitic, antibacterial, antiviral), as well as antioxidant, antitumoral  properties.

Melissa officinalis oil is suitable for topical treatment of herpetic infections.

As a medicinal plant, lemon balm:

  • relaxes body 
  • relieve stress and anxiety, promotes calmness, acting as mild sedative
  • lifts mood
  •  improves sleep
  • eases digestive disorders – gas, bloating, colic
  • fights herpes, and heals cold sores caused by herpes
  • reduces fever
  • enhances memory

How to use lemon balm

You can put melissa young leaves in salads, use it to make lemony salad dressing or marinade, or swap basil for lemon balm leaves in your favorite pesto recipe.

For making medicinal tea from lemon balm:

  1. Place a few  fresh lemon balm leaves (or 1 teaspoon of dried crushed leaves)  in a cup
  2. Pour 1 cup of boiling water over the leaves. Cover the cup to preserve essential oil.
  3. Let it steep for 5-10 minutes
  4. Strain.

Enjoy this flavorful lemony drink alone or add some honey to it.

Useful Tip

If you need short term insect repellent while working in your garden – crush few lemon balm leaves and rub them into your skin.

Alternatively, you can place a few washed lemon balm leaves in plain cold water and let it sit  for 20 minutes. This way you will get water infused with lemony scent to drink. And it is better for your body than store bought water enhancers.

You can make lemon balm infused oil, tincture or salve at home by following general guidance for creating natural remedies in this article.

Note. Consult your doctor about taking lemon balm if you are using prescribed sedative drugs to avoid amplification of sedative effect. Also, be wary of taking it if you have any thyroid problems.

 

Where to buy medicinal plant seeds?

I have never seen Korean mint plant sold at nursery. To tell the truth I didn’t see calendula or lemon balm plants for sale in the nursery either, but I guess depending on where you live you might find calendula or melissa to buy in the pot.

The easiest and cheapest way is to grow these plants from seeds. I strongly suggest to get organic seeds if you are using plants for medicinal purposes. Most likely you will need to order the seeds from a seed catalog or you can get them from Amazon. Below is a selection of organic Korean mint, calendula, and lemon balm seeds you can find on Amazon.
