The sesquiterpene lactone parthenolide accumulates in feverfew shoots and is thought to contribute to feverfew's antimigraine activity. The first part of this study examined the effects of nitrogen application and irrigation on shoot yield and shoot parthenolide concentration.

  • Native Plants for Your Backyard
    U.S. Fish & Wildlife Service Native Plants for Your Backyard Native plants of the Southeastern United States are more diverse in number and kind than in most other countries, prized for their beauty worldwide. Our native plants are an integral part of a healthy ecosystem, providing the energy that sustains our forests and wildlife, including important pollinators and migratory birds. By “growing native” you can help support native wildlife. This helps sustain the natural connections that have developed between plants and animals over thousands of years. Consider turning your lawn into a native garden. You’ll help the local environment and often use less water and spend less time and money maintaining your yard if the plants are properly planted. The plants listed are appealing to many species of wildlife and will look attractive in your yard. To maximize your success with these plants, match the right plants with the right site conditions (soil, pH, sun, and moisture). Check out the resources on the back of this factsheet for assistance or contact your local extension office for soil testing and more information about these plants.

  • The Mock-Oranges
    ARNOLDIA A continuation of the BULLETIN OF POPULAR INFORMATION of the Arnold Arboretum, Harvard University VOLUME ~Jr JUNE 18, 1965 NUMBER5 THE MOCK-ORANGES are about fifty species and varieties of Philadelphus being grown in THERE-~- the commercial nurseries of the United States, so there is a wealth of ma- terial from which to select ornamental plants. The collection at the Arnold Arboretum contams over one hundred species and varieties. They all have white flowers, their fruits are dried capsules and not very interesting, and the autumn color is not especially outstanding, being yellow or yellowish. In other words, they are chiefly of value during the short period when they are in bloom; but they are all grown easily in almost any normal soil, and are mostly free from injurious insect and disease pests-reason enough why they have proved popular over the years. Some plants in this group have special merit. Philadelphus coronarius, for in- stance, is excellent for planting in dry soil situations. Many of the hybrids have extremely fragrant flowers, and some of the plants, like P. laxus and P. X splen- dens, have branches which face the ground well all around and make fairly good foliage specimens throughout the length of time they retain their leaves. On the other hand, the flowers of many of the species are not fragrant, and some plants, like Philadelphus delavayi and P. X monstrosus reach heights of fifteen feet or more; they are frequently just too tall and vigorous for the small garden. There are better shrubs of this height with mteresting flowers, better autumn color, and fruits in the fall (like some of the viburnums), so, if tall shrubs are desired, it is not the mock-oranges which should have first consideration.

  • Fuzzy Pride-Of-Rochester Deutzia Scabra Thunb
    Weed of the Week Fuzzy Pride-of-Rochester Deutzia scabra Thunb. Common Names: deutzia, fuzzy deutzia, pride-of- Rochester, fuzzy pride-of-Rochester Native Origin: Eastern Asia - China, Japan, Korea; introduced in 1880. Description: A large deciduous shrub in the hydrangea family (Hydrangeaceae) growing to a height 6 to 10 feet and width of 4 to 8 feet with an open, arching crown. The bark is reddish brown to orange-brown and exfoliates in large sheets. Slender stems are fuzzy/scabrous, red-brown to green, with hollow piths and pointed buds. Leaves are opposite, simple, serrate, and slightly pubescent on both surfaces, giving them a rough, fuzzy/scabrous feel. Light green leaves are 4 inches long and 2 inches wide with a rounded leaf base. Flowers are white tinged with a rosy- purple color on the outside of the corolla, fragrant, and borne on a panicle to 6 inches. Flowers are produced on the previous season’s wood and appear in late spring to early summer (April – July). The fruit is a 1/4 inch dry brown capsule that ripens in early fall and persists through the winter. It reproduces through seeds. Habitat: It grows in full sun, semi-shade, or moderately heavy shade. It tolerates most soils but prefers moist well- drained fertile soils. This ornamental plant can be found in landscaped gardens, open woodlands and shady forest edges. In Kentucky state parks fuzzy pride-of- Rochester invades woodlands areas of sugar maple, buckeye, and magnolia trees. Distribution: This species is reported from states shaded on Plants Database map.

  • Taking Herbal Medications Before Surgery
    Taking Herbal Medications before Surgery The American Society of Anaesthesiologists (ASA) is cautioning those who use herbal medications to stop taking these “natural” products 1 week prior to having a surgery. Recent findings disclose that seven out of 10 herbal medicine users never tell their physicians about the herbal products they are taking. Most believe that since the products are “natural” they must be safe. Just because a medicine is called “natural” or “herbal” does not mean it is harmless or completely safe. Many of these products are quite potent and can be dangerous, especially if the patient’s anaesthetist or surgeon does not know that the patient is taking them. A number of anaesthetists have reported significant changes in heart rate or blood pressure in some patients who have been taking herbal medications. These herbal products include: Baikal skullcap root (Scutellaria baicalensis) Herb or dietary supplement Bilberry fruit (Vaccinium myrtillus) Ginkgo leaves (Ginkgo biloba) Black currant seed oil (Ribes nigrum) Ginseng root (Panax ginseng) Bladderwrack (Fucus vesiculosus) Green tea (Camellia sinensis) Borage seed oil (Borago officinalis) Hawthorn leaf and flower (Crataegus oxyacantha, Crataegus monogyna) Bromelain from pineapple fruit and stem (Ananas comosus) Horse chestnut bark (Aesculus hippocastanum) Cayenne fruit (Capsicum frutescens) Huang qi (Astragalus membranaceus) Celery plant (Apium graveolens) Kava kava root (Piper methysticum) Chamomile, German flowers (Matricaria recutita) Licorice root (Glycyrrhiza glabra) Clove oil (Syzygium aromaticum) Omega 3 Coleus roots (Coleus forskohlii) Papain from papaya leaves and unripe fruit (Carica papaya) Da huang, Chinese rhubarb root (Rheum palmatum) Pau d’arco bark (Tabebuia avellanedae) Dan shen root (Salvia miltiorrhiza) Reishi mushrooms (Ganoderma lucidum) Dandelion root (Taraxacum officinale) St.
