It is important to note that not all plants respond well when tea grounds and used tea bags are added to the soil, directly or in compost form. The natural tannic acid inside tea leaves leaches into the soil with rainwater as tea grounds decompose, thereby lowering the soil’s pH and increasing acidity. This poses a problem for plants that require neutral to alkaline soils but creates the ideal conditions for acid-loving plants to thrive. Use fresh and used tea grounds only on acid-loving plants, such as –
- Taxus baccata
Aspirin reduces the overall risk of both getting cancer and dying from cancer. This effect is particularly beneficial for colorectal cancer (CRC). It may also slightly reduce the risk of endometrial cancer, breast cancer, and prostate cancer.
Some conclude the benefits are greater than the risks due to bleeding in those at average risk. Other are unclear if the benefits are greater than the risk. Given this uncertainty, the 2007 United States Preventive Services Task Force guidelines on this topic recommended against the use of aspirin for prevention of CRC in people with average risk.
The bark of willow trees contains large amounts of salicylic acid, which is the active metabolite of aspirin. Willow bark has been used for millennia as an effective pain reliever and fever reducer.
The use of herbs to treat disease is almost universal among non-industrialized societies.
Many of the pharmaceuticals currently available to physicians have a long history of use as herbal remedies, including opium, aspirin, digitalis, and quinine. The World Health Organization (WHO) estimates that 80 percent of the population of some Asian and African countries presently use herbal medicine for some aspect of primary health care. Pharmaceuticals are prohibitively expensive for most of the world’s population, half of which lives on less than $2 U.S. per day. In comparison, herbal medicines can be grown from seed or gathered from nature for little or no cost.
The use of, and search for, drugs and dietary supplements derived from plants have accelerated in recent years. Pharmacologists, microbiologists, botanists, and natural-products chemists are combing the Earth for phytochemicals and leads that could be developed for treatment of various diseases. In fact, according to the World Health Organisation, approximately 25% of modern drugs used in the United States have been derived from plants.
Among the 120 active compounds currently isolated from the higher plants and widely used in modern medicine today, 80 percent show a positive correlation between their modern therapeutic use and the traditional use of the plants from which they are derived. More than two thirds of the world’s plant species – at least 35,000 of which are estimated to have medicinal value – come from the developing countries. At least 7,000 medical compounds in the modern pharmacopoeia are derived from plants. In many medicinal and aromatic plants (MAPs), significant variations of plants characteristics have been ascertained with varying soil traits, and the selective recovery and subsequent release in food of certain elements have been demonstrated. Great attention must be paid to choose soil and cropping strategies, to obtain satisfactory yields of high quality and best-priced products, respecting their safety and nutritional value.
Not to be confused with cactus
; nearly all cacti are succulents but not all succulents are cacti.
Succulent plants, such as this Aloe
, store water in their fleshy leaves
In botany, succulent plants, also known as succulents or sometimes fat plants, are plants having some parts that are more than normally thickened and fleshy, usually to retain water in arid climates or soil conditions. The word “succulent” comes from the Latin word sucus, meaning juice, or sap. Succulent plants may store water in various structures, such as leaves and stems. Some definitions also include roots, so that geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. In horticultural use, the term “succulent” is often used in a way which excludes plants that botanists would regard as succulents, such as cacti. Succulents are often grown as ornamental plants because of their striking and unusual appearance.
About 60 different plant families contain succulents.Cactaceae, Agavoideae, Aizoaceae, and Crassulaceae, most plants are succulents. The habitats of these water preserving plants are often in areas with high temperatures and low rainfall. Succulents have the ability to thrive on limited water sources, such as mist and dew, which makes them equipped to survive in an ecosystem which contains scarce water sources.
In some families, such as
one example is Graptopetalum paraguayense.
Mycelium is the vegetative part of a fungus, consisting of a mass of branching, thread-like hyphae. The mass of hyphae is sometimes called shiro, especially within the fairy ring fungi. Fungal colonies composed of mycelium are found in and on soil and many other substrates. A typical single spore germinates into a homokaryotic mycelium, which cannot reproduce sexually; when two compatible homokaryotic mycelia join and form a dikaryotic mycelium; that mycelium may form fruiting bodies such as mushrooms.
Through the mycelium, a fungus absorbs nutrients from its environment. It does this in a two-stage process. First, the hyphae secrete enzymes onto or into the food source, which break down biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and active transport.
Mycelium is vital in terrestrial and aquatic ecosystems for their role in the decomposition of plant material. They contribute to the organic fraction of soil, and their growth releases carbon dioxide back into the atmosphere (see carbon cycle). Ectomycorrhizal extramatrical mycelium, as well as the mycelium of Arbuscular mycorrhizal fungi increase the efficiency of water and nutrient absorption of most plants and confers resistance to some plant pathogens. Mycelium is an important food source for many soil invertebrates.
The 3 types of mushrooms that are easiest to grow at home are oyster, white button, and Shiitake. The method for growing each mushroom is similar, but the ideal growing medium differs.
Oyster mushrooms grow best in straw; Shiitakes grow best on hardwood sawdust; button mushrooms grow best in composted manure. These different growing media reflect the different nutritional needs of each species. However, each of these 3 species can be grown readily enough in sawdust or straw.
Buy mushroom spawn.
Mushroom spawn is sawdust permeated with mushroom mycelia – essentially the root structure of the fungus. It is used much like plant seedlings to facilitate growth.
Make sure to buy spawn rather than spores. Some retailers will also sell spores, which are more akin to the seeds of plants (rather than seedlings). Growing mushrooms from spores takes more time and practice, and is best suited for a seasoned mushroom grower.
