Meet the Mint Family (+ Mint Sun Tea Recipe!)

I walk in my gardens on a July evening, admiring the lush green that abounds in midsummer. The bee balm is chest high and near blooming, the lavender, catnip, and oregano are in full flower; the sage, rosemary, thyme, and basil are growing tender new leaves almost daily; and the peppermint and lemon balm are spreading prodigiously. I check the progress of the bee balm buds as I’ve lately seen a hummingbird, stick my nose in the lavender for a deep inhale, pick a few sprigs of catnip for kitty, and pinch off some basil leaves for pesto, catching the scent of each plant as I go. These plants are all beloved and widely used for culinary, aromatherapy, and medicinal purposes, and they have another important unifying trait — they are all in the mint family, Lamiaceae, which has over 200 genera and 7000 species!

Other common mint family plants include spearmint, hyssop, motherwort, marjoram, skullcap, holy basil, self heal, hore-hound and savory; not to mention the many varieties of mints, such as apple mint, chocolate mint, and pineapple mint.

Mint Family Plant Identification

Mint family plants are birds of a feather, and if you start to observe and compare them, you’ll notice they share the following characteristics:

  • Square (four-sided) stems (note that most, but not all mint have square stems, and a few non-mints have square stems but do not smell minty)
  • Pairs of opposite leaves that alternate direction and get progressively smaller towards the top of the stem
  • Tiny flowers with five united petals (two up, three down) to make upper and lower “lips” that form a tubule (perfect for hummingbirds and butterflies!)
  • Flowers arranged in whorls (clusters) at the base of the leaves or at the end of spikes
  • Strongly aromatic (almost all of the mint family plants have a strong aroma)
  • Likely sitting on your spice rack! (nearly half of common kitchen spices are in the mint family)

Medicinal Mint Family- Identifying Mint

Mint Family Herbal Medicine

The aromatic nature of the mint family plants come from their high levels of volatile oils, which also account for the rich flavors prized in cooking and many of their medicinal properties. While the medicinal actions of the mint family plants make quite a long list, many of them fit into four categories:

  • Nervine for nervous system complaints (anxiety, depression, headaches, insomnia, dementia)
  • Digestive for digestive system complaints: (indigestion, gas, cramps, nausea, colic)
  • Antimicrobial for infections: (bacterial, viral, fungal)
  • Clearing for respiratory system complaints (infection, congestion, asthma)

So how do they do it? The answer is in the volatile oils. These plants contain volatile oils such as menthol, thymol, citronellal, limonene, camphor, carvacrol, and linalool, to name a few. Anti-microbial actions aside (we’ll get to that), the primary action of volatile oils is to relax tension and spasm in our internal organs. Our powerful sense of smell is directly connected to the limbic system of the brain, which governs emotion and memory. When we catch the scent of an aromatic plant, nerve endings are stimulated to send impulses to the limbic system and to structures that manage stress in our internal organs; once the volatile oils enter our blood, they relax smooth muscles in the airways and circulatory tissues in the intestines, relieving tension and restoring balance (Masé, 2013). As for the nervine effects, the balanced state created in our internal organs is reflected in our emotional state by a feeling of “being in the flow” or feeling a sense of harmony. Masé (2013) postulates that this is most likely because new smells signify a changing environment and act as a wake up call of sorts, allowing us to move from a stressful state to a calmer state.

As for the antimicrobial action of mint family plants — in short, their volatile oils are great for killing microorganisms, from bacteria and viruses to fungi. In the Middle Ages, aromatics were used as strewing herbs in households during times of sickness and plague to combat ‘evil’, aka microorganisms. And then there’s the infamous legend of the Four Thieves, in which four brothers who set to work robbing graves during the Bubonic Plague purportedly used a blend of herbs (including lavender, rosemary, and peppermint) to protect themselves from infection. Modern day scientific research substantiates the antimicrobial action of plants in the mint family for such ailments as colds, influenza, upper respiratory infections, bronchitis, pneumonia, and herpes simplex (cold sores), just to name a few.

And what could be more heavenly than mint family aromatherapy as a sinus infection remedy? Whether it’s a cup of peppermint tea for nasal congestion, a thyme facial steam to calm coughs, or hyssop syrup to move lung congestion, the aromatic action of these mint family plants relaxes the tissue of the respiratory system and opens the airways, allowing congestion to move out and breath to flow freely.
