Cornus florida has been proven to prevent the spread of malaria. Their bark is rich in tannin and has been used as a substitute for quinine. During the civil war confederate soldiers would make a tea from the bark to treat pain and fevers, and dogwood leaves in a poultice to cover wounds


Dogwood bark is best used as an

• ointment for ague - A tincture can be made out of either the leaves or the bark of the plant and can be used to treat various ailments such as eczema, skin infections, intestinal parasites, veal skin, and gout and so on. 

The tincture should be prepared in the following: mix 50 g of the ground plant in 250 ml of alimentary alcohol. Filter this mixture for 15 days. It is advisable to consume about 10-15 drops of this tincture (after diluting in water) about three times a day.

Externally, poulticed onto external ulcers and sores.

• Jamaican dogwood is a fairly potent sedative well known as a specific for migraine headaches, neuralgia, and for treatment of insomnia caused by pain , nervous tension, and stress. The bark is anti-inflamatory and antispasmodic and can be used in cases of dysmenorrhea (painful periods). Jamaican dogwood is a strong analgesic that can be used along with other herbs to treat the musculoskeletal pain of arthritis and rheumatism. Preparation Methods & Dosage :Most often as a decoction, also taken in tincture and caps.

Formulas or Dosages

Use only dried dogwood bark. Fresh bark upsets the stomach and bowels.
Infusion: steep 1 tbsp. bark in 1 pint water for 30 minutes and strain. Take 1/2 cup every 2-3 hours.
Tincture: take 20-40 drops in water, as needed.

Folklore
 
This tropical shrub grows wild in Central America and the northern parts of South America. The bark of the root works similarly to aspirin pain relievers by blocking an enzyme that produces inflammatory and pain causing chemicals called prostaglandins. It gained its nickname "fish poison tree" from the West Indian practice of using it to stupify fish to make them easier to catch. 

Other Uses

The flowers of the plant can either be eaten raw or used in the making of syrups, brandy or marmalade.

Twigs used as chewing sticks, forerunners of the toothpick. It was sometimes used as a substitute when Peruvian bark could not be obtained. 

Biochemical Information

Forestation
 
Dogwood can be propagated without much difficulty by its seeds. The seeds of dogwood are sown in the fall into organized rows of sand or sawdust and the seedling usually emerge in the ensuing spring. If you are using clean seeds the germination rate is excellent, almost 100 per cent. In fact, the dormancy of the seeds is prevailed over by means of cold stratification treatments for about 90 to 120 days (three to four months) at around 4°C (39°F).

Alternately, dogwood may also be propagated by softwood cuttings taken from new growth in the later part of spring or early part of summer and rooted.

While the success of rooting can be as high as 50 per cent to 85 per cent, this method is not generally used by commercial cultivators.  Selected cultivable varieties are usually propagated by a method called T-budding in the later part of summer or by means of another method known as whip grafting in the greenhouse during winter months onto seedling rootstock.

Joshua Tree treat arthritis, osteoarthritis and rheumatoid arthritis, joint pain and inflammation

The Joshua tree species, one of the longest-living plants on earth.

Approaching Grand Canyon West Arizona USA, travelers pass through a Joshua Tree forest, along Pierce Ferry Rd in Mojave Desert.

Name


The tree was first named by Mormon pioneers in the nineteenth century, who thought that the upturned branches resembled the arms of the prophet Joshua, pointing the way to the promised land.


Other names: Spanish bayonet, Mojave yucca, Banana yucca

Description
 
The Joshua tree is actually a species of yucca (Yucca Brevifolia), that can reach a height of 50 feet and is believed to live for up to 1,000 years although they are difficult to date accurately - as they are not proper trees, there are no annual growth rings.

A large cluster of white or greenish flowers can appear at the end of each stem from March to May, but this requires just the right combination of springtime temperature and moisture, and several years may pass without a major blooming. Plants start to form the familiar branched appearance when they are 6 to 10 feet tall and several decades old, with new stems forming only after a flowering.
 
 Joshua trees occur in patches across several Southwest states, wherever conditions of temperature, drainage and rainfall are suitable.

This tree has a top-heavy branch system, but also has what has been described as a "deep and extensive" root system, with roots possibly reaching up to 11 m (36 ft) away.

Forestation in Desert
 
Joshua trees are fast growers for the desert; new seedlings may grow at an average rate of 7.6 cm (3.0 in) per year in their first ten years, then only grow about 3.8 cm (1.5 in) per year thereafter.

New plants can grow from seed, but in some populations, new stems grow from underground rhizomes that spread out around the Joshua tree.

Propagation
 
Seed - sow spring in a greenhouse. Pre-soaking the seed for 24 hours in warm water may reduce the germination time. It usually germinates within 1 - 12 months if kept at a temperature of 20°C.

 Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for at least their first two winters.

Plant them out into their permanent positions in early summer and consider giving them some winter protection for at least their first winter outdoors - a simple pane of glass is usually sufficient.


Medicinal Uses
 
Native Americans and Mexicans also used yucca sap medicinally to treat arthritis, joint pain and inflammation. They used sap from the leaves in poultices or baths to treat skin lesions, sprains and bleeding.
 
Thus, constituents of the yucca are used today to treat osteoarthritis and rheumatoid arthritis.

We know now that this soapy substance from the pithy insides of the yucca leaves and roots is because of their high saponin content. According to researcher Ken Wells (findarticles.com), saponins are the precursor to cortisone, which prevent the release of toxins from the intestines which restrict cartilage formation. 

Saponins have anti-tumor properties  

Other Uses

The roots of some types of yucca contain a natural detergent and were found to be effective for washing and shampooing. 

Interestingly, yucca extracts are used in beverages such as root beer and slurpies to provide the foamy ‘head.’ 

They are also used industrially in mining and ore separation, in preparation of emulsions for photographic films and extensively in cosmetics, such as lipstick and shampoo. 

The antifungal and antibacterial properties of saponins are important in cosmetic applications, in addition to their emollient effects. Yucca extracts are also used for ammonia and odor control in pig and poultry-raising facilities and in dog and cat foods (Pauling Institute).

Edible parts of Joshua Tree

Flowers - cooked. The flower buds, before opening, can be parboiled in salt water to remove the bitterness, drained and then cooked again and served like cauliflower. The opened flowers are rich in sugar and can be roasted and eaten as candy.

Fruit - cooked. The fruits can be roasted then formed into cakes and dried for later use. Root - raw, boiled or roasted.
 
Seed. Gathered and eaten by the local Indians
 
 

Medicinal Trees -Cascara (Rahmnus purshiana) bark used as effective laxative purgative and anti-cancer effects

Cascara. Rhamnus purshiana. Cascara. A small tree or shrub with greyish-black bark that grows to 10 metres tall. 

Medicinal Uses



In the Pacific Northwest and British Columbia, this small tree is called cascara buckthorn. Since 1877, its bark has been dried, baled, and shipped to dealers who grind it into a fine powder for medicinal use as an effective laxative or purgative.

Cascara is known in both the native plant as well as the medical trade. In the late 1800’s it was discovered that the bark from the Cascara tree could be used as a mild cathartic, helping the symptoms of habitual constipation. Also knonwn as Chittam, or Cascara Buckthorn.

Studies have shown that the extract from cascara bark also contains a substance called emodin, which may have anti-cancer effects.

The fruit can also be eaten cooked or raw, but has a laxative effect.

Due to its bitter taste, cascara can be used to stop nail-biting by applying it to the fingernails

Preparation

The bark is collected in the spring or early summer, when it easily peels from the tree. Once stripped from the tree, the bark must be aged for at least 1 year before use, because fresh cut, dried bark causes vomiting and violent diarrhea. This drying is generally done in the shade to preserve its characteristic yellow color. This process can be quickened by simply baking the bark at a low temperature for several hours. In her book, Major Medicinal Plants, Dr. Julia Morton suggests using a dosage of 10–30 grains, dissolved in water, or 0.6–2 cc for fluid extract.The ethnobotanist and herbalist Dr. James A. Duke suggests an effective dosage of approximately 1 to 3 grams dried bark, or 1–2.5 grams powdered bark


Native Americans Used the Tree
 
Skagit people produced a green dye from the bark. Coastal people also knew it as a tonic and as a laxative.

Cascara was harvested throughout its range for use as a laxative. Bitter cascara extract has been used in liquors and a debittered extract as a flavouring for drinks and ice cream. Honey from cascara flowers is also reported to have a mild laxative effect.

History

Spanish priests in California named the tree Cascara sagrada, meaning "sacred bark." This name has two possible origins. The first is from the medicinal properties of the bark and the second from its resemblance to wood used for the ark of the covenant. Rhamnus is the ancient Greek name for the genus.

Forestation
 
It is also planted as an ornamental, to provide food and habitat for wildlife, or to prevent soil erosion.

The Cascara tree can grow in both sun or shade. It prefers moist, well drained sites. This native tree grows from northern British Columbia south into California and east into Idaho and Montana.
