Blue Cohosh Plant Care

In This Article you will learn all about blue cohosh plant care and their growing tips and tricks. Caulophyllum is a hardy perennial that grows 50 to 90 cm tall. They feature blue-green complex juvenile leaves and green adult leaves, bloom in May, and yield lovely blue fruits. Blue Cohosh, papoose root, and squaw root are all popular names for Caulophyllum plants. Caulophyllum thalictroides is one of the Latin names for this plant.

It’s a native medicinal plant that may be found from Maine to Ontario in the north, south to Georgia in the south, and west to Missouri and Indiana in the west. It can be found in North Carolina at elevations of up to 4,000 feet and is most common in the state’s western region. It’s a herbaceous perennial that may grow up to four feet tall at maturity and can grow 18 to 22 inches every month throughout the growth season. The leaves are big and irregularly serrated, having three pinnately complex divisions. From May through July, tall plumes of cream to white flowers on wand-like flower stalks grow, reaching heights of over six feet. Seeds form in capsules that generate a rattling sound when shaken from August through October. The seeds are ripe and ready to be collected at this point.

The rhizomes and roots of black cohosh are economically valuable. The rhizome is dark brown to black in colour, thick and knobby on the top surface, and produces big buds. Fibrous roots cover the rhizomes, which are frequently concentrated on the bottom half of the rhizome. Unless otherwise noted, “root” refers to the rhizome and roots throughout the rest of this book. The root is picked, washed, and dried when the plant’s leaves begin to die back in the fall.

How to Grow Blue Cohosh Plant

Caulophyllum plants, such as blue cohosh, should be planted outside. Plant the roots 2.5cm deep in a damp wood soil with a pH of 4.5 to 7. They should be planted 30 to 40cm apart in shaded regions and spaced 30 to 40cm apart. Plants can be divided in the early fall or cuttings taken from the roots can be used to make more plants (complete with rhizomes). Blue cohosh has been used to induce labour in many people, so don’t consume it!

What is the best way to take blue cohosh?

If you’re thinking about using herbal supplements, talk to your doctor first. You might also want to talk to a practitioner who specialises in herbal/health supplement use. If you decide to take blue cohosh, follow the package directions or the instructions given to you by your doctor, pharmacist, or other healthcare practitioner. Do not use more of this product than the label suggests. If the problem you’re treating with blue cohosh doesn’t improve or grows worse while you’re using it, contact your doctor. Herbal/health supplement standardised extracts, tinctures, and solid formulations may deliver a more consistent dosage of the substance. Take blue cohosh pills with a full glass of water.

Measure the liquid forms of blue cohosh with a dropper or a dosage-measuring spoon or cup to guarantee the precise dose. Some types of blue cohosh may be made into a tea that can be consumed.

Unless expressly instructed by a health care expert, do not use multiple blue cohosh formulations (e.g., pills, liquids, teas, and others) at the same time. Taking multiple blue cohosh formulations at the same time raises the danger of an overdose. Blue cohosh should be stored as directed on the box. Blue cohosh should be kept away from light and moisture in general.

Common Uses of Blue Cohosh

Blue cohosh is a black cohosh medicine that has a lot of uses. Blue cohosh is a supplement that can be taken as a tablet or made as a tea. Most people know that Blue Cohosh is used to treat menopausal and menstrual problems, but it has also been used to help women who are very pregnant go into labour.

Blue Cohosh’s Potential Negative Effects

Blue cohosh raises a slew of major safety issues. The berries are deadly, and there have been a few reports of youngsters being seriously ill as a result of eating them.

The root irritates mucous membranes, while the leaves and stems irritate the skin and induce contact dermatitis. Chest discomfort, gastrointestinal irritation, severe diarrhoea, cramps, high blood glucose levels, and high blood pressure are some of the side effects linked with the herb’s use.

Preparations containing blue cohosh can disrupt a woman’s menstrual cycle and cause her to give birth on a different schedule than nature intended. Although the plant has been used to stimulate uterine contractions for generations, it recently has been discovered that it contains alkaloids that are poisonous to the foetus.

As a result, it is not advised that pregnant or nursing women consume the plant. Other herbs and conventional drugs, such as heart and blood pressure medications, may interact with blue cohosh. As a result, people with heart problems should avoid using the plant.

  • chest discomfort that is fresh or intensifying;
  • a light complexion, blue lips, or blue fingernails;
  • a sense of dizziness, as if you’re about to pass out;
  • high blood sugar—increased thirst, increased urination, hunger, dry mouth, fruity breath odour, drowsiness, dry skin, blurred vision, weight loss; or low blood sugar—increased thirst, increased urination, hunger, dry mouth, fruity breath odour, drowsiness, dry skin, blurred vision, weight loss; or Severe headache, blurred vision, pounding in your neck or ears, nosebleed, anxiety, disorientation, severe chest discomfort, shortness of breath, irregular heartbeats are all signs of dangerously high blood pressure.

Seeds for Propagation

Seeds of black cohosh can be used to reproduce the plant, however germination can be uneven and/or difficult. When black cohosh seeds ripen on the plant, they have an immature embryo and require a period of warm/cold stratification to break seed dormancy and allow germination to begin. The physiological dormancy of black cohosh seeds is quite weak, with most seeds germinating after only 8 weeks of cold stratification. During the late summer and fall months, the quickest approach to assure proper stratification is to gather the seeds as they mature on the plant and sow them right away.

When the seed pods transform from green to dark brown and the seeds rattle inside the capsule when shaken, the seeds are mature and ready to gather. By planting immediately, the seeds will be exposed to the seasons’ natural temperature changes and will complete their stratification process without the need for any more treatments.

Growing Black Cohosh: Common Issues and Solutions

While black cohosh is generally healthy, it does face some pests and illnesses from time to time.


Cutworms are night-flying moths’ caterpillars. They have the potential to wreck havoc in the garden. They devour the ground-level stems and emerge at night. We’ve created a guide to assist you in combating this pest.

Blister Beetles

They are a kind of beetle that feeds on Leaves, flowers, pollen, and other insects are eaten by blister beetles. They will occasionally discharge fluid onto your skin, producing mild blistering that will heal within a few days. Birds will remove the bugs off the plant for you if you let them into your forested area. For a rapid knock-down, use organic pyrethrum.Offset Damping

When black cohosh is young, it will be affected by this. A fungal disease causes the plant to decay at the stem and roots below the surface. It’s easy to overwater black cohosh when attempting to keep it wet. Our tutorial will show you how to deal with this typical problem.

Spot on the Leaf

On the leaves, spots appear, generally with light centres and dark margins. This fungus is frequently caused by a lack of ventilation and too much moisture. Make a solution using baking soda and water. In a gallon of water, dissolve 1/2 teaspoon baking soda and spray generously. If that doesn’t work, try a fungicide containing sulphur or copper.

Black Cohosh Harvesting

Harvest in the fall when the roots are at their most abundant. Remove the whole root and rhizome system. If you want to save any of the rhizomes for future planting, do so right now. You may also keep them at 40°F in burlap sacks. Ensure that they have enough of air and don’t rot. Normally, black cohosh is dried or dehydrated and stored until it is needed. Black cohosh roots have a decent market, so you’ll probably be able to sell your harvest if you want to. It will take four to six years for rhizomes to grow large enough to harvest utilising the seed approach. In around three years, you should be able to harvest plants that were grown from rhizomes. Check to see if harvesting wild black cohosh is allowed in your region before doing so. Due to over-harvesting and selling, several regions have declared it illegal.

Fertilizer for blue cohosh plant care:

You’ll need to mimic these circumstances in your garden since black cohosh thrives in woodland regions with abundance of organic materials. When you plant, use a lot of well-rotted compost and continue to side dress it with compost throughout the year. Leaves should be mulched around the plants and replaced as needed. Apply a slow-release fertiliser in the spring if the plant seems stunted.Water for blue cohosh plant care

This is a plant that requires a lot of water. Black cohosh prefers a moist habitat and grows in shady, forested regions. It prefers free-draining soil with lots of water. Keep the soil wet but not waterlogged by watering often.

Staking and Pruning for blue cohosh plant care

In the spring, give it a good pruning. The flower show will be more spectacular as a result of this. In the fall and winter, the white flowers are frequently the last blossoms.


Rhizome cuttings and seed can be used to grow black cohosh. The rhizomes should be separated in the spring or fall in the first scenario. While plants may be established from seed inside, rhizome planting produces the greatest results and allows for a speedier harvest.

Cut the rhizomes into parts that are roughly 2 – 3 inches (5 – 8 cm) in length to proliferate from rhizome divisions. Allow the fibrous root to stay linked to the rhizome parts if it exists.

Plant the rhizome parts upright, 4 to 6 inches (10 to 15 cm) deep, and two inches (5 cm) deep in the soil. Make that the rhizome portion is erect and that the plantings are spaced 18 to 24 inches (45 to 61 cm) apart. Black cohosh is a slow-growing plant, and an above-ground stalk may take a year or more to form. The plant will, however, ultimately grow a large number of shoots, albeit it may take up to five years. Over the winter, let the seeds and stalks alone and trim them back in the spring. Because black cohosh grows so slowly, it may never need to be divided, but this method is great for propagation.

 Proper Storage for blue cohosh plant care

After harvesting black cohosh, any soil, sand, pebbles, and foreign debris that may have become adhered to the rhizomes must be removed. Rhizomes can be hand-washed or cleaned in a root washer. The roots should be dried whole under low heat with consistent circulation once they have been cleaned.

A customised herb drier or food dehydrator could be more effective. After drying, keep the rhizomes in burlap bags or cardboard boxes in a cool, dark, and dry location. It’s best to keep dried black cohost for no more than a year.

If the rhizomes were taken for planting stock, they should be shook to remove any dirt, pebbles, or foreign material before planting. If the rhizomes are not planted right away, they should be protected from the sun to prevent the roots from drying out.

Fresh rhizomes should be kept in mesh or burlap sacks in a cold setting with damp sphagnum moss. It’s necessary to stir the roots every now and then to allow for air and avoid fungal growth.

Blue cohosh plant  washing

Roots should be properly cleansed after harvesting to eliminate any dirt, debris, and foreign root material. To properly eliminate all undesired debris, it may be necessary to rupture the root. Soak roots in a pail of water for a few minutes to soften any adhering dirt and debris, then spread them out over a wire mesh screen and spray with a medium-pressure hose. Dirt can also be removed from hard-to-reach locations with a tiny soft-bristle brush. Root washers, whether mechanical or manual, can be employed and may be a preferable option for cleaning huge amounts of root debris.

If you want to keep your roots fresh, mix them with damp sphagnum moss and store them in mesh/burlap bags or cardboard boxes in the fridge (40°F). Aerated roots should be monitored for symptoms of dryness, mould, and rotting on a regular basis.

Blue cohosh plant drying

To protect product quality and ensure product integrity during long-term storage, roots must be carefully dried. Spread roots evenly on a wire mesh screen and dry for 7-10 days, or until totally dry, in a dark, well-ventilated room with good airflow and temperatures between 85 and 95 degrees Fahrenheit (Davis and Persons, 2014). In humid climates, temperatures as high as 130°F may be required to completely dry out the roots (Davis, 2016).

The roots should be checked for indications of mould or rotting on a regular basis, and contaminated parts should be removed from the room if found. Select a few medium-sized roots from the batch and break them in half to assess whether the drying process is complete. When thoroughly dry, the roots should snap cleanly but not be too brittle.

After drying, agitation can be used to clean the roots further. Excess dirt and debris that remained on the root after the initial washing become loosened and can be knocked free from the root when agitated because the roots shrink throughout the drying process. Because agitation can separate numerous fibrous roots, it may be required to screen the debris in order to recover as much botanical material as possible. The particle size of the materials to be sifted will determine the size of the sifting screen utilised.

Advantages and uses

blue cohosh tincture

The majority of black cohosh’s possible advantages are connected to women’s health or hormonal balance. There is, however, insufficient evidence to support its usage for any of these illnesses, with the exception of menopause symptoms.

Menopause and signs of menopause

The majority of individuals take black cohosh to relieve menopausal symptoms, and it’s one of the uses with the most compelling data.

In a study of 80 menopausal women who were suffering hot flashes, those who took 20 mg of black cohosh daily for 8 weeks had much fewer and milder hot flashes than those who did not take the supplement.

Furthermore, comparable findings have been validated in additional human research. Though further research is needed, black cohosh looks to be helpful in reducing menopausal symptoms .


Although you may encounter claims on the internet that black cohosh will help you become pregnant or enhance your fertility, there isn’t much research to back this up.

Black cohosh, on the other hand, appears to boost the efficiency of the fertility medicine Clomid (clomiphene citrate) in infertile couples, increasing their chances of becoming pregnant

In three small human investigations, women with infertility who took black cohosh pills combined with Clomid had an increase in pregnancy rates or ovulation


Black cohosh contains estrogenic activity, which means it mimics the hormone oestrogen and may aggravate breast cancer or raise your risk of breast cancer

The majority of research, however, demonstrate that black cohosh has no effect on the incidence of breast cancer. Taking black cohosh was linked to a lower risk of breast cancer in two human trials. Black cohosh extract showed anti-estrogen action in test tubes, slowing the spread of breast cancer cells.

Mental well-being

Black cohosh may offer some mental health benefits, especially in postmenopausal women.

The use of herbal supplements for anxiety and depression in menopausal women was studied in a review of trials. Supplementing with black cohosh had little effect on anxiety, but it was associated to considerable improvements in psychiatric symptoms, according to researchers. Still, additional study is needed to completely comprehend the influence of black cohosh on mental health.


Although there is limited evidence that black cohosh helps promote sleep, it may aid menopausal women with symptoms like hot flashes who are creating sleep difficulties.

However, a small research of 42 menopausal women revealed that taking black cohosh supplements improved sleep quality and duration. Another study found that a combination of black cohosh and other components, such as chasteberry, zinc, ginger, and hyaluronic acid, reduced hot flashes linked to sleeplessness and anxiety.

Loss of weight

As oestrogen levels gradually decline in menopausal women, they may be at an increased risk of undesired weight gain. Because black cohosh has estrogenic properties, it may have a slight favourable effect on weight control in postmenopausal women.

However, there is just a smattering of evidence to back this position. More and bigger human studies are needed to determine whether there is a relationship between black cohosh and weight loss, if there is one.

Blue cohosh vs black cohosh

Blue cohosh is a North American native that is most commonly found along the east coast. Caulophyllum thalictroides is its Latin name, but it’s also called blue ginseng, papoose root, yellow ginseng, blueberry root, and beech drops.

The roots of blue cohosh are the sole portion of the plant used in most supplements. The plant’s bluish-green hue and blue fruits distinguish it. When young, these plants are purple and grow to be between one and three feet tall. Because black cohosh has dark brown or black roots, it’s simple to tell the difference between blue and black cohosh. Both blue and black cohosh are indigenous to North America.

Despite the fact that they belong to separate families, they have a common name, and both plants have been used to cure women’s health issues in the past. Consult your doctor or a certified health care provider for advice on how to use these and other therapeutic herbs safely and effectively.

Final Thoughts on Blue Cohosh Plant Care

Hope you all about blue cohosh plant care. Although blue cohosh has been used in the past to alleviate some menopausal symptoms, it has been linked to major adverse effects such as breast cancer. Furthermore, because blue cohosh contains significant quantities of harmful compounds, it is not generally utilised as a herbal supplement nowadays.

Other therapies that don’t have the same adverse effects as blue cohosh may be more successful. Non-estrogenic herbs, for example, are an excellent treatment for menopausal symptoms. More information may be found in the following article.
