Poisonous Plant – Stinging Nettle Urticacea (Urtica dioica) Indetification : erect, tall, square perennial plant with a grooved stem studded with stinging hairs; dark green, rough, heart-to oval-shaped, and toothed leaves; green blooms that are born in the leaf axils and produce a profusion of green seeds. one plant having both sexes and a few plants with distinct sexes. Habitat: roadsides, peripheral areas, marshes, marshy places, fields' edges, and streamsides across the country. Toxins and irritants: acetylcholine, histamine, choline, and formic acid. Symptoms: rash that instantly burns and itches when it comes into contact with stinging hairs. First Aid: limited in scope; certain individuals are more vulnerable than others. Applying mullein leaf or the juice from spotted touch-me-nots, also known as jewelweed (Impatiens capensis), to the affected area works well. Just smash the leaves and stems and rub the area. Remark: nettles are used to massage arthritic joints; they are a counterirritant. It is not advised to whip the arthritic area as this would only offer short respite from pain and inflammation. It is approved by commission e for the treatment of benign prostatic hyperplasia (bPH). Prostate enlargement symptoms have been effectively treated with a combination of saw palmetto and nettle root. In Russia, tincture made from nettle roots that have been soaked and processed in alcohol is used to treat gall bladder irritation and hepatitis. In the US, nettle root extract has also been studied for the management of prostatic hyperplasia.

Poisonous Plant – Poison Sumac Anacardiaceae (Rhus vernix) Identification: 7–15 leaflets with white fruit (berries hanging from delicate stalks), shrub growing to 10' with compound leaves. Habitat: Eastern United States wetlands, bogs, marshes, and hemlock forests. irritants/toxins: urushiol. Symptoms: comparable to those of poison ivy and poison sumac, itching, blistering, inflammation, and contact dermatitis are caused by this. First Aid: As soon as possible (up to an hour or even two hours) after exposure, wash your skin thoroughly with soap and water to remove any oils before they have a chance to infiltrate your skin. Wash all clothes and tools well because the oil can linger on them for up to a year. Itching can also be reduced by taking tepid—not hot—water baths with baking soda and/or oatmeal. When used topically, calamine lotion helps sores dry out and reduces itching. Over-the-counter treatments are available that include hydrocortisone, a steroid that can lessen irritation and reduce inflammation. Prescription steroid creams are equally effective but include a higher quantity of hydrocortisone. Note: I once unintentionally snapped off a poison sumac branch and used it as a staff while trekking. The extent of the rash on my body the day after the climb was astounding and depressing.   Poison Oak - Poison Oaks Anacardiaceae (Toxicodendron diversiloba) Identification: a tiny plant with more deeply cleft lobes than poison ivy. The leaves are hairy, glossy, and stemless. Habitat: Usually found in California's canyons and mountain valleys in the West. an eastern variant as well. irritants/toxins: urushiol. Itching, redness, and contact dermatitis are the symptoms. First aid: treat with benadryl, calamine lotion, and oatmeal baths; in extreme situations, use prescription or over-the-counter prednisone and other anti-inflammatory drugs. Similar to poison ivy and poison sumac.   Poisonous Plant - Poison ivy (Toxicodendron radicans) Anacardiaceae Identification features include a hairy, climbing vine or shrub, three-striated leaves, and pale yellow or white fruit. With hairs, vines cling to trees. Habitat: Fence rows, fields, waste ground, woods, and dunes, pretty much wherever from coast to coast and north to south. Toxins/irritants: Urushiol, an oily resin. Contact dermatitis symptoms include inflammation, blistering, reddening, and itching, which can last for many days. First Aid: Avoid the sun when you have facial inflammation. Use jewelweed, also known as spotted touch-me-nots, to soothe itching and redness. Calamine lotion, tricalm without steroids, Zanfel wash, and corticosteroids like prednisone are just a few medicinal treatments available. The dermatitis usually goes away on its own in two weeks or less. Remark: This rash and its accompanying discomfort can often be avoided by giving the area a good scrub down with soap and water within an hour of contact.  Poisonous Plant – Hops cannabaceae (Humulus lupulus) identification: climbing perennial with pencil-thick stems that do not turn woody. The plant spreads and climbs through shrubs. The opposite, three to five-lobed, and serrated leaves. Male flowers are small, inconspicuous, and have a yellowish green color. A fruit cone emerges from the several florets that make up female flowers. cone's color might range from yellow to gray based on whether it's dried or fresh. The bitter alkaloid is found in the cone's scales. Habitat: This plant, which has evaded agriculture, is found in meadows, marshes, and the margins of wooded areas. Cultivated areas can be found in northern Idaho, Canada, the Okanagan region of Washington, northeastern Washington state, and east of Seattle. Toxins/irritants: Allergy symptoms have been reported when hops, pollen, and leaves have come into contact. The plant and, in certain cases, a bacteria on the plant (Pantoea agglomerans) are the cause of the dermatitis; fertilizers and pesticides have been ruled out as the cause. Certain hop oils and acids cause positive reactions in allergy-sensitive people. Contact dermatitis is the symptom. Workplace risk for those who grow and harvest beer crops for the beer business; also a brewery risk for dermatitis. It's interesting to note that a hops water-soluble extract has prevented rats from ovulating. It usually appears on the sides of the fingers as tiny, weeping papules and vesicles. First Aid: keep distance, mask, gloves, and long sleeves. The condition is limiting itself. Notes: Although later study has not supported the initial findings, floral tea may have estrogenic effects. German Commission E authorized for use as a sleep aid to treat anxiety and insomnia. Studies on animals and in vitro cultures have demonstrated the antibacterial, antifungal, and anticancer properties of the plant's flavonoids. It is a diuretic, just like a lot other plant teas. In experiments on mice, humulon decreased the mean number of tumors in animals given cancer. In a different human trial, hops along with motherwort, valerian, and balm helped alcoholics sleep better. In related studies, the University of Chicago is finishing up a study on hops' ability to effectively induce sleep. Related research indicates that melatonin is a reasonably safe substitute for hop allergy sufferers. Hops can be added to a clean pair of panty hose, tied off, and submerged in hot bath water for a soothing steam bath. Alternatively, construct a sweat lodge out of a dome tent, cover it with a blanket and tarp, and that, heat the stones over an open flame until they are hot. Then, put the stones in a sizable metal container that has been enameled and transfer it to the tent's floor. To prevent scorching the floor of the tent, set the metal tub on boards. Use a long-handled ladle to gently dip water over the rocks, then place hops and cedar boughs soaked in water on the heated stones. The resulting steam will provide therapeutic scents to warm the cabin. Some reports claim that smoking hops may have a slight sleepy effect. To produce a sleep aid, mix a 6-ounce cup of hot water—just off the boil—with roughly 1 teaspoon of dried flowers. Cover, let cool, then sip.  Poisonous Plant - Hogweed, Giant Hogweed umxbelliferae (Heracleum mantegazzianum) Identification: resembles cow parsnip in appearance, but usually much larger (up to 12'), with white flowers, hollow stem, and more deeply divided leaves. Habitat: East and west of the Mississippi, plants found in marshes, lakeshores, and along streams. common in garbage areas. a foreign invader from the Far East. Toxins/irritants: furanocoumarins, or psoralen. Symptoms include blisters, redness, and inflammation that are more severe than those of cow parsnip or other umbelliferae plants—a plant that many believe should be avoided or completely exterminated. I find this plant to be rather stunning; like us, it enjoys the natural beauty of this place, but beware of its ominous repercussions, which can linger for months or even years. Avoidance is first aid. Recognize juices and stay away from them. It should be noted that despite its reputation as a villainous plant, it is unable to walk and does not bite. Be cautious since it punishes those who fail to recognize it and then come into contact with its fluids.  Poisonous Club – Devil ‘s Club Araliaceae (Oplopanax horridus) identification: shrubby perennial to 10', a twisted tangle of spiny thorns. gives off a pleasant scent and has big, maple-like leaves that are thorny on the underside. White blooms in a terminal head that resembles a club. habitat: seeps, stream banks, damp, low-lying forests—common in the Olympic range and cascades, from sea level to the tree line in Canada—and western mountains to the west coast, particularly in moist places. Toxins/irritants: This plant causes mechanical harm. Big thorns rip and puncture the flesh. Berries don't taste good. Symptoms: Intense puncture wounds that in certain cases might lead to dermatitis. First Aid: clean cuts and apply triple antibiotic ointment if necessary. Notably, spring buds are consumed as a survival food (remember, though, that people will also eat dirt during bad times). Seek them out early, as soon as the snow melts, and select tender new shoots with gentle spines. This resilient plant fortifies every habitat in which it grows. Uses for its roots, berries, and greenish bark make this one of the most significant medicinal plants in the West. Berries are applied to hair to eradicate lice and impart a glossy finish. Inner bark can be consumed raw by chewing it or it can be decocted and ingested for the same purpose. The inner bark is used to treat ulcers, arthritis, and cramping in the stomach and intestines. See the author's Basic Illustrated Edible Wild Plants and Useful Herbs or go to his website, herbvideos.com, for additional resources.  Poisonous Plant -Cow Parsnip umbelliferae (Heracleum lanatum) Identification: huge umbels of white flowers, enormous, deeply cut leaves, hollow stem; resemblance to angelica and numerous other members of the carrot family. Odorous plant up to 7 feet tall; in the West, usually smaller. Habitat: East and west of the Mississippi, wetlands, lakesides, and streamsides; also common along rivers, streams, and trails in the Mountain West. Toxins/irritants: furanocoumarins, or psoralen. Blisters, irritation, and redness are the symptoms. Avoidance is first aid. Recognize juices and stay away from them. Most of the time, casual touch made while hiking won't result in any symptoms. Rashes can last for several weeks or months. Note: a stem that can be eaten raw, boiled, candied, or with its skin removed. Brew roots are supposed to relieve flatulence. It is thought that fresh root makes a useful poultice. After pounding the root, apply. compounds that have been connected in both in vitro and in vivo research to cancer.  Poisonous Plant - Angelica umbelliferae (Angelica atropurpurea, A. sinensis) identification: With a strong, towering purple stem, A. atropurpurea is a tall biennial that can grow up to 9'. big compound leaves that have three to five leaflets each with a hollow petiole. Sheaths envelop emerging upper leaves, and they persist around the petioles. Clusters of greenish-white flowers resemble umbrellas. Habitat: Found in the northern tier of states, usually east of the Mississippi, in moist lowlands and near streams and rivers. Toxins/irritants: furanocoumarins, or psoralens Symptoms include a severe burn, inflammation, and pain that follows from the phototoxic reaction. First Aid: Keep plant liquids and leaves away from your skin. After coming into touch with plant juice, or if plant pieces have been consumed, spend a whole day out of the sun. Remarks: Angelica, like other umbelliferae, contains calcium channel blockers, which enhance peripheral circulation. These medications are comparable to those used to treat angina. Numerous other umbelliferae, such as parsley, celery, carrot, and Queen Anne's lace (wild carrot), can be phytophototoxic to sensitive people or induce contact dermatitis. Those who are prone should wear long sleeves, pants, and gloves when gardening. Decoctions made from the roots of A. atropurpurea were used by Native Americans as a gargle for sore throats, rheumatism, fevers and chills, and flatulence. Additionally, the herb was utilized in sweat lodges to treat headaches, frostbite, hypothermia, and arthritis. To alleviate pain externally, crush the root and apply it as a poultice (avoid direct sunlight). I have casually touched both this plant and cow parsnip while hiking, and nothing bad has happened. Despite being recommended for psoriasis, angelica hasn't worked for me. Eating angelica is supposed to increase your sensitivity to ultraviolet radiation by swallowing psoralens. The uV-light/psoralen interaction may halt or inhibit skin cell division after ten minutes in the sun. Psoralens taken on oneself and then exposed to light can be carcinogenic and phototoxic. For a safe and effective psoriasis wash, visit herbvideos.com. roots that are used to grilled fish, gin, vodka, and different jams to add flavor.  Poisonous Plant – Yaupon, Yaupon Holly Aquifoliaceae (Ilex vomitoria) Identification: Yaupon is an evergreen holly that resembles a shrub and has glossy, green leaves with pointed tips. Simple, alternating leaves with shallow teeth. Small white blossoms on a bush give rise to scarlet berries. Habitat: coastal plant that is commonly farmed and found in Texas and the Southwest. Triterpenoids, saponic glycosides, and illicin are among the poisons that make berries hazardous and inedible. Symptoms include nausea, vomiting, and diarrhea due to mild poisoning. First Aid: disease progresses naturally and self-limits. Note: colors are made from berries and leaves. Alum mordant is dyed red by the juicy red berries. Use it on wool by soaking it in the dye and allowing it to absorb the color in the sunshine. To attain a gray hue, pound leaves in water containing iron or copper. Young leaves can be consumed or used to make tea.  |
