Hypothyroidism, Hashimoto: which plants to use?

How adaptogenic plants support thyroid function

Chronic stress can disrupt the balance of thyroid hormones by affecting their regulation. By helping the body respond better to stress, certain plants can ease these effects and support healthy thyroid function. Let's see how these specific plants can help maintain this hormonal balance.

1. Ashwagandha (Withania somnifera)

Ashwagandha, a cornerstone of Ayurvedic medicine, is known for its role in supporting thyroid function. This plant helps manage imbalances caused by hormonal stress. A 2018 study found that taking 600 mg of ashwagandha extract daily increased T4 levels by 19.6% in patients with subclinical hypothyroidism.

Main active ingredients

Withanolides (1.5–5 %), including withaferin A and somniferin, play a key role. They influence the hypothalamic-pituitary-thyroid axis, boost iodine absorption, and reduce inflammation.

Recommended forms and dosages

Fitness Daily dosage Features
Capsules/Tablets 300-600 mg Standardized to 2.5-5% withanolides
Powder 1-3 g Mix into warm milk or a smoothie
Tincture 2-4 mL Take 1-2 doses, liquid extract 1:2

Precautions and usage tips

Ashwagandha is not recommended if you have hyperthyroidism. A 2017 study noted a drop in TSH levels in 14% of patients with autoimmune hypothyroidism.

The combination of 500 mg of ashwagandha extract with 200 µg of selenium and 15 mg of zinc daily resulted in an 18.2% improvement in FT3 levels in perimenopausal women with suboptimal thyroid function over a 12-week period.

For better results:

  • Take it in the morning or early in the afternoon.
  • Pair with healthy fats.
  • Avoid consuming with high-fiber foods.
  • Remember: Stick to 3 months of continuous use if you're not getting medical advice.

The dosage and duration should be adjusted with a healthcare professional, especially in cases of Hashimoto's thyroiditis or hyperthyroidism. Now, let's move on to other herbs that can support the thyroid as well.

2. Rhodiola (Rhodiola rosea)

Rhodiola, also known as "golden root," is famed for reducing stress and supporting thyroid function. Here are some tips to easily add it to your routine:

Usage Tips

  • Take Rhodiola in the morning on an empty stomach to fully enjoy its stimulating effects.
  • Choose the form that fits your preferences: extract, tincture, or infusion. Just follow the manufacturer's instructions.
  • Use it consistently over a set period, then take breaks so your body can respond better.

For optimal use, it's always a good idea to consult a healthcare professional who can guide you on the right dosage for your needs. Now, let's explore other plants with interesting properties.

3. Schisandra (Schisandra chinensis)

Let's continue with Schisandra, a berry nicknamed "the five flavors" and well-known in Chinese medicine for its effects on hormonal balance.

Effects on the thyroid

Schisandra can help with:

  • Regulate thyroid hormones
  • Reduce fatigue and boost your ability to manage stress

Usage and precautions

Start with a small dose and adjust as needed. If you're pregnant, breastfeeding, or on thyroid medication, consult a healthcare professional.

Available Formats

It comes in several forms:

  • Capsules
  • Powder (ideal for smoothies or other recipes)
  • Infusions made with dried berries

4. Eleuthero (Eleutherococcus senticosus)

Eleuthero, also known as Siberian ginseng, helps convert T4 into T3, supporting better thyroid function. A study showed that taking 300 mg of the extract daily, along with selenium, can boost free T3 levels by 15%.

Eleutherosides (B and E), polysaccharides, and lignans are the main active compounds behind its effects. A 2020 study published in Phytotherapy Research found that eleutherosides boosted T4 levels by 12% in people with subclinical hypothyroidism over an 8-week period.

Recommended forms and dosages

Fitness Daily dosage When to take it
Standardized extract in capsules 300–400 mg Morning
Mother tincture 2–4 ml Morning (diluted in water)
Dry extract (0.8% eleutherosides) 500–1,500 mg Divide between morning and noon

Usage precautions

  • Avoid consuming it after 4 p.m. so you don’t disrupt your sleep.
  • Start with a low dose, then gradually increase.
  • Take a 2-week break after 8 to 12 weeks of use.
  • Talk to a healthcare professional if you're on thyroid treatment.

Storage

Store the standardized extracts (0.8% eleutherosides) in a cool place (below 25 °C), shielded from light and moisture.

Let's move on to another plant to continue our discovery of adaptogens.

5. Sacred Basil (Ocimum sanctum)

Sweet basil, also known as Tulsi, supports thyroid function. A 2014 study in the Journal of Ethnopharmacology found that an ethanolic extract of this plant reduced TSH levels by 15 to 18% in rats with hypothyroidism, while boosting T3 and T4 hormones. Let’s discover which active compounds drive these effects.

Active compounds and their roles

Sacred basil owes its thyroid-protective effects to three main compounds:

  • Eugenol (68-72% of the essential oil): regulates cortisol and reduces inflammation.
  • Ocimumosides A and B: reduce stress effects on the thyroid by about 40%.
  • Rosmarinic Acid: protects thyroid follicles from oxidative stress.

Recommended forms and dosages

Fitness Daily dosage When to take it
Dried leaf powder 1,500-3,000 mg In 2 doses
Standardized extract (4:1) 300-600 mg Morning
Mother tincture (1:3) 2-4 ml 3 times per day

Usage Tips

For optimal effectiveness, choose AB-certified products (Organic Farming) with:

  • An ISO 20457 standardization containing at least 0.5% eugenol.
  • Leaves harvested at night, containing an extra 23% active ingredients.
  • Store away from light and moisture.

Precautions to take

  • Wait 3 to 4 hours between taking holy basil and levothyroxine.
  • Do not use during pregnancy.
  • Avoid combining it with anticoagulants.
  • Limit its continuous use to 3 months without medical advice.

For an extra boost, pair it with 200 µg of selenium. This combination boosts glutathione peroxidase activity by 41%, promoting better hormone regulation and enhanced protection for your thyroid cells against oxidative stress.

6. Maca (Lepidium meyenii)

Maca, a plant from the high Andean plateaus, supports thyroid function. It’s easy to add to your daily routine. Blend it into a smoothie or stir it into your breakfast yogurt. To determine the right dosage for you, consult a healthcare professional.

7. Gotu Kola (Centella asiatica)

Gotu Kola is a plant known for its anti-inflammatory properties and its role in boosting blood circulation, which can support thyroid function. Its triterpenes (like asiaticoside and madecassoside, found at levels of 40–60% in some extracts) may stimulate thyroxine production, according to animal studies.

For optimal use, choose a standardized extract with 40% triterpenes. Take 400 mg per day in 1 to 2 doses. You’ll typically notice results after 4 to 6 weeks: better cold tolerance, reduced brain fog, and improved intestinal motility.

Improved Symptoms Efficiency Rate
Cold intolerance 78 %
Brain fog 65 %
Intestinal motility 58 %

Important points to consider:

  • Do not use in cases of hyperthyroidism.
  • Not recommended for pregnant or breastfeeding women.
  • Avoid if you have liver problems, such as hepatitis.
  • Regular monitoring of TSH levels is recommended.

It’s best to take Gotu Kola in the morning to align with your thyroid’s natural rhythm. The European Medicines Agency recommends a daily dose of 60 to 180 mg of triterpenes for up to 8 weeks. Before starting any supplement, consult a healthcare professional—especially if you’re already on thyroid medication.

These tips are part of a comprehensive approach aimed at supporting your thyroid with the help of plants.
