Saffron's aroma is often described by connoisseurs as reminiscent of metallic honey with grassy or hay-like notes, while its taste has been noted also as hay-like and some what bitter. Saffron also contributes a luminous yellow-orange colouring to foods. Because of the unusual taste and colouring it adds to foods, saffron is widely used in Persian, Arab, Central Asian, European, Indian, Iranian, Moroccan and Cornish cuisines. Confectionaries and liquors also often include saffron. Common saffron substitutes include safflower (Carthamus tinctorius, which is often sold as "Portuguese saffron" or "assafroa") and turmeric (Curcuma longa). Medicinally, saffron has a long history as part of traditional healing; modern medicine has also discovered saffron as having anticarcinogenic (cancer-suppressing),[ anti-mutagenic (mutation-preventing), immunomodulating, and antioxidant-like properties. Saffron has also been used as a fabric dye, particularly in China and India, and in perfumery.

Honey:Medicinal uses and health
Honey is primarily a saturated mixture of two monosaccharides. This mixture has a low water activity; most of the water molecules are associated with the sugars and few remain available for microorganisms, so it is a poor environment for their growth.
A study found that certain anti-oxidants and vitamins are found in honey in concentrations similar to those in some fruits and vegetables.
Hydrogen peroxide in honey is activated by dilution. However, unlike medical hydrogen peroxide, commonly 3% by volume, it is present in a concentration of only 1 mmol/l in honey. Iron in honey oxidizes the oxygen free radicals released by the hydrogen peroxide.
glucose + H2O + O2 → gluconic acid + H2O2
When used topically (as, for example, a wound dressing), hydrogen peroxide is produced by dilution with body fluids. As a result, hydrogen peroxide is released slowly and acts as an antiseptic.
Topical honey has been used successfully in a comprehensive treatment of diabetic ulcers when the patient cannot use other topical antibiotics.
The pH of honey is commonly between 3.2 and 4.5. This relatively acidic pH level prevents the growth of many bacteria.
According to recent findings, honey may have some significant nutraceutical effects (or positive long-term health effects resulting from honey's consumption). In addition to its primary carbohydrate content, honey often contains polyphenols, which can act as antioxidants. Antioxidants in honey have even been implicated in reducing the damage done to the colon in colitis.Furthermore, some studies suggest that honey may be effective in increasing the populations of probiotic bacteria in the gut, which may help strengthen the immune system, improve digestion, lower cholesterol and prevent colon cancer.
Some studies suggest that the topical use of honey may reduce odors, swelling, and scarring when used to treat wounds; it may also prevent the dressing from sticking to the healing wound. Honey has been shown to be an effective treatment for conjunctivitis in rats. Honey (especially when combined with lemon) is often taken orally by pharyngitis and laryngitis sufferers, in order to soothe them. Though widely believed to alleviate allergies, local honey has been shown to be no more effective than placebos in controlled studies. This may be due to the fact that most seasonal allergies are caused by tree and grass pollens, which honeybees do not collect.

Honey and Islamic tradition
The Qur'an mentions rivers of honey in paradise.
"And thy Lord taught the bee to build its cells in hills, on trees and in (men's) habitations...there issues from within their bodies a drink of varying colours, wherein is healing for mankind. Verily in this is a Sign for those who give thought".
There is entire Sora in Qur'an called (the Bees) alnahl. According to the hadith of Bukhari, Muhammad liked honey and other sweet things. Prophet Mohammed strongly recommend honey for healing purposes.

Medicinal mushrooms
Currently, many species of mushrooms and fungi utilized as folk medicines for thousands of years are under intense study by ethnobotanists and medical researchers. Maitake, shiitake, and reishi are prominent among those being researched for their potential anti-cancer, anti-viral, and/or immunity-enhancement properties. Psilocybin, originally an extract of certain psychedelic mushrooms, is being studied for its ability to help people suffering from mental disease, such as obsessive-compulsive disorder. Minute amounts have been reported to stop cluster and migraine headaches.
