Dipsacus fullonum commonly known as Teasel is a species of flowering plant known by the common names Fuller’s teasel, Common teasel, Teasel, Venuscup teasle, Wild teasel, Draper’s teasel, Card Teasel, cardère Sylvestre, Common Teazle, Fuller’s Teazle, Indian teasel and cut-leaved teasel. The plant is native to Eurasia and North Africa, but it is known in the Americas, southern Africa, Australia and New Zealand as an introduced species and often a noxious weed. The plant belongs to Dipsacus L. genus and Dipsacaceae (Teasel family). Genus name comes from the Greek dipsa meaning thirst (flowering stems are clad with paired leaves whose united bases form small basins which typically collect rain water). The specific epithet of fullonum and a sometimes used common name of fuller’s teasel both indicate this plant was once used in “fulling” (process of shrinking and weaving cloth after weaving). Early wool manufacturers attached the seed heads (covered with stiff, hooked points) to a spindle for the purpose of teasing (combing) cloth to raise the nap. Additional common names for this plant include Adam’s Flannel, Church Broom, Prickly Back, and Water Thistle.

Plant Description

Teasel is a tall, somewhat spiny, herbaceous, robust, biennial prickly and monocarpic perennials plant that grows about 7 to 10 feet (2-3 m) tall. The plant is found growing in mesic prairies (especially cemetery prairies), degraded grassy meadows, creeks, savannas, woodland borders, pastures and abandoned fields, landfills, roadsides, and waste areas, roadsides, ditches and in pastures, old fields, riparian areas and forest edges. The plants grow on a variety of soils from sandy soils with abundant moisture to heavy clays in poorly drained areas. The plant has stout taproot with a fibrous secondary root system that are more than 2 feet (0.6 m) long and 1 inch (2.5 cm) in diameter at the crown. Erect, hollow, hairless stems are pale green to reddish green. They have scattered white prickles and flat longitudinal ridges.

Leaves

Opposite leaves are up to 12 inches long and 3inches across. They are green, yellowish green, or reddish green, lanceolate to linear-lanceolate, ascending to spreading, and rather stiff in texture. Their margins are smooth, slightly prickly, or irregularly toothed. On the upper surface of each leaf, there is a white central vein, while on the lower surface this vein has stout prickles. The lower opposite leaves are sessile, while the upper opposite leaves are perfoliate or clasping. All leaves are hairless. The leaves are fused around the stem forming a saucer-like shape that holds rainwater.

Flowers & Fruits

Teasel flowers occur in terminal, stiff, egg-shaped heads that are up to 4 inches (10 cm) long. The entire flower head (peduncle) measures anywhere between 50 and 100 centimeters in height and consists of tiny individual flowers that measure 10 to 15 mm long. Inflorescences contain 250 to 1,500 flowers, which bloom for only 1 day. Flowering begins in the middle of the inflorescence and then progress up and down. Often there are few flowers blooming at the same time. Flower heads are subtended by linear bracts that are about 4 times as long as they are wide. Individual flowers, which are 2/5 to 3/5 inch long, consist of white petals united into a tube with 4 purple lobes. Below each cluster are several long, slender, stiff, bracts that curve upward. Within the cluster, there are many short, stiff bristles. Once mature, flower clusters become dry, hard, and persistent. Teasel flowers appear between late June and September. Flowers are followed by light brown, ridged, hairy, and 4 angled achenes that measure up to 8 mm long. Enclosed in each fruit is a single seed. Seeds are small and are spread by the wind after the seed-head has dried.

Health Benefits of Teasel

Teasel plant consists of several health-benefiting vitamins and minerals. Listed below are few of the health benefits of teasel

1. Treats fracture risk. সহজ বাংলা: হাড় দুর্বল হয়ে ভাঙার ঝুঁকি বেশি।" data-rx-term="osteoporosis" data-rx-definition="Osteoporosis means weak, fragile bones with higher fracture risk. সহজ বাংলা: হাড় দুর্বল হয়ে ভাঙার ঝুঁকি বেশি।">osteoporosis and osteopenia

Teasel is widely used in traditional Chinese Medicine as a liver and kidney toner. Teasel Root is categorized as a Yang tonic with an affinity for assisting with structural repair especially of connective tissue and bone. It increases circulation and aids in building strong tendons and bones. Apart from that teasel root helps damaged bone tissue grow, stimulating new bone growth. It also helps alleviate muscle pain. Recent research shows that Teasel Root helps strengthen and build bone mass, particularly in porous trabecular bone.(1)

2. Helps rid the body of chronic Lyme disease

Lyme disease is normally caused by a bacteria (Borrelia burgdorferi), transmitted to humans by infected black-legged ticks. Symptoms vary, but can include fever, fatigue, headaches, and a skin rash. A couple of weeks of antibiotics can help clear Lyme disease from the body. Chronic Lyme disease, however, is something many people suffer from. Chronic Lyme disease happens when antibiotics fail to heal the body, and fatigue, headaches and other symptoms linger, often longer than six months. Teasel Root is not an bacterial infections. সহজ বাংলা: ব্যাকটেরিয়ার সংক্রমণের ওষুধ।" data-rx-term="antibiotic" data-rx-definition="An antibiotic is a medicine used to treat bacterial infections. সহজ বাংলা: ব্যাকটেরিয়ার সংক্রমণের ওষুধ।">antibiotic, but a weed that is capable of changing the body’s environment, so the body can kill off Lyme bacteria. The body’s muscles and cells are stimulated and it helps dump Lyme bacteria into the bloodstream, and then the body can detox it. (2)

3. Natural diuretic

Teasel Root is considered an excellent diuretic, making it wonderful for clearing the body of excess water weight, as it encourages the flow of urine. This dynamic root also encourages sweating, which is another way to rid the body of toxins (sweating acts as a diuretic). It rids the body of unneeded salt and water, which can also help with tissue swelling (infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation).

4. Helps treat Candida overgrowth

Although Candida is present in everyone’s bodies, it is a fungus, and when it gets out of control, it can result in various maladies such as yeast infections, depression, chronic fatigue, or infection of our gut flora. Teasel Root works with natural antibiotics, and aids in purging excess Candida into our bloodstream so that it can die-off. Inulin is part of the Teasel Root, and helps probiotic growth in the colon. Probiotics, which are live bacteria and yeasts, are good or helpful bacteria. It’s the stuff that keeps our guts healthy. Pro means for, and bio in this definition means life; therefore, probiotics are for life. Taking teasel root if you have candida overgrowth can force candida from tissues, and the exposure allows probiotics to attack and conquer the offending enemies.

5. Jaundice

Jaundice is a common liver problem. The appearance of light or a dark-yellow coloring of the skin and eyes is known as jaundice. Jaundice is not a disease, but can be related with other problems, such as acute infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation of the liver, alcoholism, liver infection or cancer, and bile duct inflammation. Elevated bilirubin is an orange-yellow substance made during the normal breakdown of red blood cells. Bilirubin passes through the liver and is eventually excreted out of the body, and causes the yellowing of skin and/or eyes.” The diuretic properties of Teasel Root support the liver to clear the body of toxins.
