  • Herbalists' Views on the Top-Selling Herbs (Part 9): Aloe & Flax + New Market Data!
    Sep 22 2025

    This week we continue our investigation into the best-selling herbal supplements in the US. First, an update: the 2024 Herbal Market Report data is here!

    The overall picture is very similar to the 2023 data, with most items on the lists simply changing position. The overall market had a 5.4% increase, topping out above $13.2 billion for the highest annual sales on record. Direct-to-consumer commerce – via websites like Amazon, for instance – continues to be the largest fraction of sales.

    In the mainstream list, the biggest story is the increase for “mushrooms (other)”, which reached #26 despite not appearing at all in prior years. This listing includes lion’s mane, turkey tail, and other mushrooms – but not chaga, cordycpes, or reishi (those are tracked individually). Also of note, the sales numbers for saint john’s wort in 2023 were adjusted to the tune of a $20 million increase! This would place SJW at #17 on that year’s list, instead of being absent from it. This makes much more sense, since SJW has been such a popular herb for so long.

    In the ‘natural expanded’ list, the most notable increase came for “algae (other)”, which would exclude spirulina & blue-green algae as well as chlorella. Sea moss / Irish moss (Chondrus crispus), as well as other seaweeds, are the big drivers of this increased interest in “algae (other)” – largely due to TikTok trends around ‘detox’ and ‘cleansing’. Mullein, moringa, milk thistle, rhodiola, chaga, and oregano also had >20% increases, while the biggest decrease in sales came for wheatgrass/barleygrass, continuing a slow decade-long slide.

    Today’s herbs, aloe and flax, are both plants whose modern incarnations and sales points are quite different than their historical applications. In the case of aloe, the stimulant laxative effect of its latex was historically its most valued power. Today, it’s more popular for the gentle demulcent/emollient effects of its gel. As for flax: its oil is very susceptible to oxidation and was previously used in things like paint and varnish more than for human consumption. Today, cold-pressed & refrigerated oil, or fresh-ground seeds, can be a good source of anti-inflammatory omega-3s and other essential fatty acids.

    24. Aloe – Aloe vera

    • Aloe in King’s American Dispensatory (1898)
    • Aloes in A Modern Herbal, M. Grieve (1931)
    • Aloe vera at Herbal Reality

    25. Flax seed / Flax oil – Linum usitatissimum

    • Linum in The Eclectic Materia Medica, Harvey Wickes Felter (1922)
    • Flax in A Modern Herbal, M. Grieve (1931)


    Flax & aloe are two examples of soothing demulcent herbs, which can calm irritated & inflamed guts. Our course on Digestive Health discusses the effects of demulcents as well as carminatives, antispasmodics, vulneraries, and other key categories of herbs which can help resolve the whole range of digestive upsets. Hippocrates said “all disease begins in the gut”, and supporting this critical system is often key to unlocking chronic health problems.

  • Aging Is OK, Don't Freak Out
    Sep 16 2025

    When Ryn first met Katja, she was in the habit of inflating her age a bit. Why? Because as an herbalist – at that time – it was preferable to present as older, even as an ‘elder’, if possible. Times have changed, and now “influencerbalists” dominate the social media world’s public face, for herbalism as for so many things. Staying young forever looks almost plausible, when it’s shown through short-form videos on a tiny screen…

    It’s not, though. We’ll all age, and that will mean some things don’t work as well as they used to, don’t feel as good as they used to, don’t heal as fast as they used to. We’ll get tired, our hair will thin, our faces will wrinkle. All the amazing new products and one-weird-tricks will not stop these things from happening.

    We don’t need to stop them. They’re part of life. In just the same way that yes, it’s OK to be a plus-sized herbalist, it’s OK to be an aging herbalist. Chasing immortality is a fool’s errand, and it can distract both from more effective means of mitigating discomforts, and from the benefits this stage of life brings. (Yes, they exist: perspective, experience, even a peaceful detachment – these are the purview of the elder.) Aging is OK.

    We do have some herbs to recommend, though! In this episode we discuss…

    • ginseng (Panax ginseng) – Famously an “herb for elders”, and indeed able to raise energy levels, enhance congnition, improve stress responses, and much more. Yet ginseng will be much, much more effective if its influences are supported by nourishing food and frequent low-level movement.
    • solomon’s seal (Polygonatum biflorum) – Our very favorite herb for restoring moisture, and thus flexibility, to the joints and connective tissues. You can purchase a solomon’s seal salve from Healing Spirits, or find tinctures, salves, and other sol’seal remedies from Cortesia.
    • nervines, e.g. blue vervain (Verbena hastata), hawthorn (Crataegus spp.), heather (Calluna vulgaris), linden (Tilia spp.) – Consider working with nervines both for day-to-day mental & emotional steadiness, but also as aids to intentional introspection. Walking or sitting while pondering your past and present, with the support of nervine herbs, is a practice that will help you process your experiences and understand your current stage of life more deeply.
    • demulcents, e.g. linden, marshmallow (Althaea off.), sassafras (Sassafras albidum), elm (Ulmus spp.) – As we age, we tend to dry out! These herbs help us remain fluent and soft. For elders, it’s often good to combine these with carminatives such as fennel, ginger, or cardamom.

    If you’d like to start taking care of your body for the long haul – no matter what age you are today – our Community Herbalist program will equip you to do so! This program prepares you to support your family & community with holistic herbal methods.

    Like all our offerings, this bundle of self-paced online video courses comes with free access to twice-weekly live Q&A sessions with us, lifetime access to current & future course material, open discussion threads integrated in each lesson, an active student community, study guides, quizzes & capstone assignments, and more!

  • Herbalists' Views on the Top-Selling Herbs (Part 8): Milk Thistle & Black Cohosh
    Sep 5 2025

    Herbs #22 and 23 on the top-selling herbs list for 2023 were milk thistle and black cohosh.

    Today we continue our series on commercially popular herbs, and share our views as herbalists on the actions, benefits, and applications of these.

    Milk thistle is widely known as an excellent herb for the liver, and this is a case where the common wisdom is correct. It’s one of the safest herbs out there, and fortunately, it is also widely available and inexpensive. Hepatoprotective and even able to regenerate damaged liver tissue, it is at the same time a very gentle and benign plant. But don’t try to make tea with it!

    Black cohosh’s reputation is as a remedy for PMS and menopausal symptoms, and often this is attributed to phytoestrogenic activity or constituents. The reality is murky – and has remained so despite decades of argument and investigation on both sides of the claim. Regardless, black cohosh can often help. We find it best to view the herb through the lens of its action as a relaxant. If PMS or menopause are showing up with lots of tension, it’s worth a try and most likely to help. But we can also apply that action much more broadly, for injuries, spasms, and (certain kinds of) headaches.

    22. Milk Thistle – Silybum marianaum

    • Milk Thistle: Herb of the Week
    • Milk Thistle at Herbal Reality
    • Milk Thistle in A Modern Herbal, M. Grieve, 1931 – presented in this text alongside multiple other thistles, which allows for close comparisons among them.

    23. Black Cohosh – Actaea racemosa

    • Wuttke, W., Seidlová-Wuttke, D. Black cohosh (Cimicifuga racemosa) is a non-estrogenic alternative to hormone replacement therapy. Clin Phytosci 1, 12 (2015). doi: 10.1186/s40816-015-0013-0.
    • Mohapatra S, Iqubal A, Ansari MJ, Jan B, Zahiruddin S, Mirza MA, Ahmad S, Iqbal Z. Benefits of Black Cohosh (Cimicifuga racemosa) for Women Health: An Up-Close and In-Depth Review. Pharmaceuticals (Basel). 2022 Feb 23;15(3):278. doi: 10.3390/ph15030278. PMID: 35337076; PMCID: PMC8953734.
    • Black Cohosh at Herbal Reality
    • Cimicifuga in King’s American Dispensatory, 1898 – has an impressively long list of indications and applications for this remedy.


    If all you’d heard (before today) about black cohosh was that it’s “good for menopause”, you might want to check out our Reproductive Health course! We discuss the whole range of human reproductive variability and herbal medicines to support all kinds of people. We even bust a few reproductive-health myths and herban legends. (Hint: vitex is not “a miracle herb for all women”!)

  • Support the Resistance - An Herbalism Clinical Skill
    Sep 1 2025

    When you’re using your herbal skills to help others – whether you’re doing that as a Clinical Herbalist in private practice, volunteering in your community, or even just caring for your own family – it becomes obvious pretty fast that your herbal knowledge is only part of the skillset you need.

    You also need to creatively adapt what you know, so that it will actually work in that person’s life. Since every body is different, different strategies work for different people. Holistic herbalists are never trying to present “one right way” that everyone has to adhere to.

    Which means that as herbalists, we need to be creative and flexible. We need to match our strategies to each person’s life individually – and that creativity can be challenging!

    That’s one of the skills that we teach in our Clinical Skills course. Today’s episode is a segment of content on this topic, from that course, which we wanted to share with you. It’s self-contained, but it’ll also give you a peek into what our course material sounds like.

    When we talk to a client, we listen to their health goals and priorities. We also form our own understanding of the case, and our own thoughts about what to prioritize – which herbs and interventions to try first. Here’s the thing: their priorities are more important than ours! If we discern some fundamental factor they aren’t aware of, it’s our job to teach them why it’s a priority. It’s our job to educate and negotiate – not to dictate.

    Sometimes we’ll propose an idea and the client will be uncertain, or will outright reject it. When this happens, it’s not helpful to insist they follow our instructions. That’s not the relationship we have as herbalists – we’re not doctors, giving “orders”. So when the client expresses some resistance, we respect it. That respect may look like offering more information and context, or it may look like going in another direction entirely.

    The motto for this mindset is: Support the resistance.

    It’s easier said than done – but learning to do it is something we consider essential to the herbalist’s skillset.


    If this episode caught your attention, then our Clinical Skills course is for you! Learn to practice legally, safely, collaboratively, and effectively. Get all your client forms & scheduling systems sorted. Cultivate consultation interview skills, and explore methods for planning personalized protocols. Everything you need to be a top-notch herbalist!

    Like all our offerings, this self-paced online video course comes with free access to twice-weekly live Q&A sessions with us, lifetime access to current & future course material, open discussion threads integrated in each lesson, an active student community, study guides, quizzes & capstone assignments, and more!

  • Herbalists' Views on the Top-Selling Herbs (Part 7): Tribulus, Pycnogenol, Garlic
    Aug 1 2025

    On the top-selling herbs list for 2023 (the most recent data), the herbs in places #19-21 were Tribulus terrestris, Pycnogenol (an extract of Pinus pinaster), and garlic. Today we continue our series on commercially popular herbs, and share our views as herbalists on the actions, benefits, and applications of these ones.

    The pine extract is an interesting item, given that it’s not an entry for the herb itself but rather for a specific proprietary extract from one species. It’s true that this extract has been well-studied and shown to exert good effects, but it’s also true that pine is much more than this one product.

    Today’s trio also offers an excellent opportunity to apply herbal energetics to help us critique and navigate marketing hype. While tribulus is very popular as a body-building aid, its cooling nature tells us that it is most helpful for those who already run hot. Garlic is the polar opposite of that. While garlic is very famous for its capacity to lower blood pressure and cholesterol, these effects are not as straightforward in a hot, dry, tense body – garlic could cause adverse effects for such a constitution. So, looking through the lens of herbal energetics remains one of our best methods for matching the right herb to the right person.

    Every herbalist should understand energetics, and be able to apply them effectively. Our Energetics & Holistic Practice course has all the info you need to understand herbal actions, qualities, tissue states, and constitutions. These critical concepts set herbalism apart from other healing modalities and are essential to effective herbalism.

    Like all our offerings, this self-paced online video course comes with free access to twice-weekly live Q&A sessions with us, lifetime access to current & future course material, open discussion threads integrated in each lesson, an active student community, study guides, quizzes & capstone assignments, and more!

    That course is one part of our Community Herbalist program. This program prepares you to support your family & community with holistic herbal methods.

  • Mutual Aid Startup Guide
    Jul 26 2025

    Mutual aid projects are a natural place for herbalists to gravitate, and setting one up in your community is easier than you think! Our mutual aid startup guide is a free resource we offer you to help with this. You can download it right here:

    Mutual Aid Startup Guide

    In today’s episode we want to emphasize two key things about this: First, it doesn’t have to be an enormous undertaking. You can start with a small circle of friends, and build from there. The keys are consistency and continuity of communication.

    Second, getting started can be very simple! So often, people feel hesitant to begin – thinking they need a fully fleshed-out concept and perhaps some financial backing before they start. But mutual aid can be something that fits into your schedule and that lifts you up instead of burning you out.

    We discuss three examples to show what mutual aid can look like at different scales: a small personal support network, a medium community fix-it club, and a larger community disaster response team.

    We hope this episode inspires you to get started, and if you have any questions, reach out to us!

  • Thinking Through Herb-Drug Interactions

    Sussing out herb-drug interactions is complicated! In this episode we take the example of Celexa + skullcap, and demonstrate the process of investigation we’d use to sort out whether a proposed risk is real.

    We start with the Botanical Safety Handbook, because it has certain features which make it significantly better than other manuals or databases. These include the varied relevant experience and skills of the editorial team, its clarity about real vs theorized reactions, and other critical data points which are directly relevant to the herbalist’s practice.

    Checking one resource isn’t sufficient, though. We also need to consider the fact that ‘absence of evidence is not evidence of absence’, and remember that constitutional variations can significantly change the efficacy of a given herb for a particular person. Information outside of scientific studies – such as the popularity of an herb or the prevalence of a drug, as well as traditional practices with plants – can help us to orient ourselves more precisely.

    For further education about herb-drug interactions:

    • Herb-Drug Interactions & Herb Safety – our complete course on this subject teaches you all the ins & outs of identifying potential interactions, avoiding them, and conducting reality checks on information you encounter about these risks.
    • The Botanical Safety Handbook – our #1 resource for this information.
    • HHP 101: How Herbs Are Different From Drugs – a key episode of our podcast, these concepts are helpful when learning how HDI may occur.

  • Herbalists' Views on the Top-Selling Herbs (Part 6): Saw Palmetto, Cinnamon, Echinacea
    Jul 4 2025

    Our semi-annual 20% off Sale is active now!
    For the entire month of July,
    use code hawthorn at checkout
    to take 20% off all our online courses!


    On the top-selling herbs list for 2023 (the most recent data), the herbs in places #16-18 were saw palmetto, cinnamon, and echinacea. In today’s installment of our best-sellers series, we share our views as herbalists on the actions, benefits, and applications of these herbs. All three are long-term residents on the market report’s top 40 chart, and there’s no reason to expect that to change in the coming years.

    In this series of episodes, we’re working to present you with the perspective of a practicing clinical herbalist on these very popular plants. In the form of supplements, they’re among the most-taken and most-asked-about herbal remedies for the modern population. Their presentation in the marketplace, though, is generally quite restricted and limited in comparision to both historical and contemporary herbal practices!

    These herbs are “good for” more than just what’s on their packaging. Let’s break them out of their pigeon-holes and appreciate their depth & complexity together!

    If you’re new to studying herbs, these episodes will armor you with protection against “herban legends” and misinformation about these plants, which is sadly very common throughout the internet of today.

    If you’re already a practitioner, well, you know how valuable materia medica study has been, is, and will ever be! Because these supplements are so popular, you can expect many of your clients to be taking them already, and to ask you about them when they come to see you. Best to be prepared.
