If such chemical markers were used, each batch of the product would have the same health effects. However, the constituents responsible for the effects of most botanicals are not known. This belief is not necessarily correct because the safety of a botanical depends on many things, such as its chemical makeup, how it works in the body, how it is prepared, and the amount used.
The actions of botanicals range from mild to powerful. A botanical with mild action might have subtle effects. Chamomile and peppermint , for example, are usually consumed in teas to help with digestion and are generally considered safe for most people. Some botanicals with mild action might need to be taken for weeks or months before their full effects are achieved.
For example, valerian might help users sleep better after a few weeks of use, but just one dose is rarely effective. In contrast, a powerful botanical produces a fast result. Green tea a natural source of caffeine and yohimbe , for example, can have strong and immediate stimulant effects. The dose and form of a botanical preparation also play important roles in its safety.
Teas, tinctures, and extracts have different strengths from one another. For example, the same amount of a botanical may be contained in a cup of tea, a few teaspoons of tincture, or an even smaller amount of an extract. Also, different preparations have different amounts and concentrations of constituents extracted from whole botanicals. For example, peppermint tea is generally considered safe to drink, but peppermint oil is much more concentrated and can be toxic if used incorrectly.
In fact, you should always talk with your healthcare provider about botanical and other dietary supplements that you are using or are thinking of using. Determining the quality of a botanical dietary supplement product from its label is difficult. The degree of quality control depends on the manufacturer and others in the production process. The presence of terms such as "standardized", for example, does not necessarily indicate that the product is of high quality.
The U. Food and Drug Administration FDA has established good manufacturing practices GMPs that dietary supplement manufacturers must follow to help ensure the identity, purity, strength, and composition of their dietary supplements. These GMPs can prevent the use of the wrong ingredient or too much or too little of the right ingredient and reduce the chance of contamination or improper packaging and labeling of a product. The FDA periodically inspects facilities that manufacture dietary supplements.
They are often added toward the end of the cooking process. Fine herbs are used in salads or eaten raw. Dill, basil, and parsley are considered mild and fine herbs.
As far as what an herb garden should look like and how big it should be, is all left for the gardener to decide. While a garden devoted to just growing herbs and laid out in a meticulous fashion can be a charming addition to the landscape, such gardens are not necessary and are often not very practical. Herbs lend themselves to being incorporated into the vegetable garden and mix nicely with either perennial or annual flowers.
A few square feet allotted to growing herbs outside the kitchen window or along the patio can also serve the needs of those wanting a few fresh herbs.
Herbs planted where they can be brushed against while walking in the garden can add a fragerance to your garden. Many make attractive hedges, ground covers or edges along walkways. Their foliage color and texture blends in well with just about any planting. Herbs are extremely useful and attractive when used in containers.
A single herb can be grown in a container as a specimen plant or several herbs can be planted together to give the balcony or patio gardener a functional culinary herb garden. Herbs are easy to grow. Just follow a few basic cultural requirements.
Most herbs do best in full sun. There are a few that will tolerate partial shade. Any good garden soil is satisfactory for growing herbs. It is suggested that adequate amounts of organic matter such as compost or well-rotted manure be worked into the soil prior to planting. What are Trees — Definition, Structure, Importance 4. Herbs are seed-producing, non-woody plants. They die at the end of a growing season. Parts of herbs are valued for its medicinal and aromatic qualities.
Herbs contain an unbranched stem. The three types of herbs are biennials, perennials, and annual herbs. Biennial herbs take two years to complete their lifecycle. Perennial herbs live more than two years. Annual herbs complete their lifecycle within one year. Culinary herbs are used in small amounts to provide flavor to food. Perennials like lavender or thyme, biennials like parsley, and annuals like basil are used as culinary herbs. Shrubs are woody plants that contain several main stems arising near the ground.
The height of a shrub is less than 13 feet, and the diameter of the stem is around 3 inches in diameter. Shrubbery refers to an area of a garden cultivated by shrubs. A flowering shrub is shown in figure 2. Figure 2: A Flowering Shrub. Trees are woody, perennials with a single trunk, growing to a considerable height.
The lateral branches of a tree occur at some distance from the ground. The height of a tree should be at least 13 feet. The diameter of a tree should be at least 3 inches.
