Perilla and the Treatment of Allergy

Perilla (Perilla frutescens Britt.), a traditional Chinese herb, has recently received special attention because of its beneficial effects in the treatment of some kinds of allergic reactions without the side effects associated with some other used antiallergy medicines. In this chapter, the authors present a review of the problem of allergy and the current favorable evidence for the use of Perilla products towards its resolution. The Allergy Problem Allergy is an abnormal immune reaction of the body to allergens such as pollen, dust, certain foods, drugs, animal fur, animal pets, animal excretions, feathers, microorganisms, cosmetics, textiles, dyes, smoke, chemical pollutants and insect stings. Certain conditions such as cold, heat, or light may also cause allergic symptoms in some susceptible people. Some allergens are just specific to some individuals but not to others. Allergens may act via inhalation, ingestion, injection or by contact with the skin. The resulting allergy may cause the victim to have a medical problem such as hay fever (allergicrhinitis), or atopic dermatitis (eczema), or allergic asthma, with symptoms ranging from sneezing, rhinorrhea, nasal itch, obstruction to nasal air-flow, loss of sense Read more […]

Application of Perilla Leaf Extract for Allergy

In addition to the factory made Perilla products, several other methods for Perilla preparation are available in the folklore of China and Japan (). The application of home made Perilla extract is also used for the treatment of allergy. However, the removal from the extract of agricultural chemicals and perillaldehyde, which might be allergens to some individuals is important (). Administration of Perilla Leaf Extract Dr. Oyanagi et al. reported their experiences in treating allergy patients with Perilla products (). According to the different symptoms and the condition of the patients administration may be singly or combined (). Oral administration For the concentrated products of Perilla extract, the dose was 0.3-2 ml/50—100 ml water or other drink, 2-3 times daily dependent on the age. With home made or diluted extract, the dosage varied with the concentration and methods of preparation. Nasal application To relieve the symptoms of an itching or running nose, the Perilla extract was applied inside the nostrils using a cotton bud. Topical application of Perilla extract Application to the skin was helpful in relieving the itching and redness. Topical use of Perilla cream and soap For some atopic dermatitis, Read more […]

The use of eucalyptus oils in consumer products

Insect repellents As noted in the introduction, Eucalyptus citriodora oil has been used as a ‘natural’ insect repellent. Depending on the product formulation it is used in, Lemon Eucalyptus (known as Quwenling in China) is up to four or five times more effective and longer-lasting than citronella oil (from Cymbopogon nardus), one of the best known natural insect repellents. p-Menthane-3,8-diol is the main active component of Quwenling and this can be isolated and used as a highly effective insect repellent. Eucalyptus citriodora oil contains up to 80–90 per cent citronellal, along with geraniol, both of which are known to have insect repellent activity but tend to dilute the much higher activity of the p-menthane-3,8-diol. The Mosi-guard Natural insect repellent spray produced by MASTA in the UK contains ‘Extract of Lemon Eucalyptus’ and claims on the label: Approved and recommended by the London School of Hygiene and Tropical Medicine. Field trials have shown effective protection for 6 h after a single application in mosquito infected areas. Also protects against many other biting insects. Mosi-guard Natural is made from a natural and renewable resource. It is kind to your skin and has no adverse effects Read more […]

A Clinical Investigation of Perilla Extract Cream for Atopic Dermatitis

Atopic dermatitis is one kind of allergic disease. Allergies are very closely associated with an immune response. When the human body is invaded by a foreign substance (antigen), antibodies or sensitised lymphocytes will be produced as a result of the response of the immune system. Later when the same antigen invades the body again, it will soon be eliminated or become harmless to the body. This is an immune response which is an indispensable function to prevent infection and tumours. However, sometimes the immune reaction between antigen and antibodies or sensitised lymphocytes can cause harm to the body itself. This kind of immune reaction in which antigen comes from outside the body causes allergic disease, whereas antigen which comes from the body itself causes auto-immune disease. According to the statistical investigation in 1992 by the Ministry of Welfare of Japan, 34% of the Japanese population suffer from some kind of allergy, and most of them are children between the age of 0 to 4. There is the tendency for allergic symptoms to appeal- as atopic dermatitis in childhood and to become asthma or rhinitis as they mature. The word atopy is derived from Greek () and means odd and thus atopic dermatitis is Read more […]

Pepper in traditional medicine and health care

Pepper is one of the most important and unavoidable drugs in Ayurveda, Unani and Sidha, the Indian systems of Medicine. It is used as single drug or in combination with long pepper (Piper longum) and dry ginger (Zingiber officinale) the combination is popularly known as “Trikatu” — the three acrids which cures the three disordered humours-Vata, Pitta and Kapha and helps to maintain normal health. Maricham, the Sanskrit word for pepper literally means that which facilitates numbness of the tongue (“Mriyate Jihwa Anena Iti Maricham” i.e. the pungent property of the drug obstructs the sensory nerve endings of the taste buds). It also has the property of dispelling poison (“Mriyate Visham Anena”). The various Sanskrit synonyms of the drug given in ayurvedic texts of India describe its characters and different uses. According to these classics, pepper is pungent and acrid, hot, rubefacient, carminative, dry corrosive, alternative, antihelminthic and germicidal. It promotes salivation, increases the digestive power, gives relish for the food and cures cough, dyspnoea, cardiac diseases, colic, worms, diabetes, piles, epilepsy and almost all diseases caused by the disorders of vata and pitta. Pepper is prescribed Read more […]

Chamomile: Traditional Use and Therapeutic Indications

Traditional Use Chamomile has been known for centuries and is well established in therapy. In traditional folk medicine it is found in the form of chamomile tea, which is drunk internally in cases of painful gastric and intestinal complaints connected with convulsions such as diarrhea and flatulence, but also with inflammatory gastric and intestinal diseases such as gastritis and enteritis. Externally chamomile is applied in the form of hot compresses to badly healing wounds, such as for a hip bath with abscesses, furuncles, hemorrhoids, and female diseases; as a rinse of the mouth with inflammations of the oral cavity and the cavity of the pharynx; as chamomile steam inhalation for the treatment of acne vulgaris and for the inhalation with nasal catarrhs and bronchitis; and as an additive to baby baths. In Roman countries it is quite common to use chamomile tea even in restaurants or bars and finally even in the form of a concentrated espresso. This is also a good way of fighting against an upset stomach due to a sumptuous meal, plenty of alcohol, or nicotine. In this case it is not easy to draw a line and find out where the limit to luxury is. Clinic and practice Preliminary remark The suitability of the empirical Read more […]

Adverse Reactions Associated with Echinacea and Other Asteraceae

Fifty percent of Australians report using some form of complementary alternative medicines (CAM) apart from vitamins in any 12-month period, with similar patterns of use in British and North American subjects. Despite the common perception that “natural therapy” is safe, toxic and hypersensitivity reactions to complementary and alternative medicine have been described. Given that these products are rarely packaged in childproof containers, accidental exposure also occurs. Allergic reactions are most common in atopic subjects. This is not surprising when one considers that up to 20% of atopic subjects use CAM. Furthermore, these patients are more likely than others to become sensitized to cross-reactive allergens and some use (or are advised to use) products such as Echinacea for treatment of allergic disease. When interpreting reports of immediate hypersensitivity to Asteraceae-derived CAM, it is helpful to bear in mind a number of important concepts: (1) exposure to Asteraceae is common; (2) sensitization is more common in subjects with preexistent allergic disease; (3) there is allergenic cross-reactivity between different Asteraceae, and between Asteraceae and some foods; and (4) patients sensitized by inhalation Read more […]

Sinusitis

If the sinuses become congested and inflamed following a cold, flu or chronic catarrh, this can predispose to a sinus infection, either viral or bacterial. The resultant pain and swelling around the nose and eyes, as well as headaches and even toothache, can be quite distressing for children. Nasal congestion, sinusitis, postnasal drip and the irritating cough that can accompany it respond well to herbal treatment and dietary changes. Chronic sinusitis can also be related to overproduction of mucus in an attempt by the body to cleanse itself of toxins that are not being adequately eliminated elsewhere. Lack of fresh air and exercise, constipation and insufficient fluid intake and urination can all be contributory factors. Sinusitis can also be caused by atmospheric pollution such as passive smoking. Alternatively blockage and infection in the sinuses can be related to over-production of mucus due to food intolerance, most often to cow’s milk and milk products. Atopic diseases such as rhinitis are a common feature of cow’s milk allergy. A diet that reduces mucus, avoiding milk, sugar, wheat and excess red meats, and includes plenty of fresh fruit and vegetables, seeds, and essential fatty acids is recommended. Read more […]

Hayfever

Hayfever (Allergic Rhinitis) Strictly speaking, hayfever is an allergic reaction to grass pollen, which usually occurs at its worst in May, June and July, often a stressful time for children as it is exam time. The term was originally related to symptoms caused by dust when haymaking and now includes a variety of seasonal allergic reactions due to pollen or some other airborne substance. Although most of the symptoms of over-sensitivity of the respiratory mucosa caused by hayfever are more annoying than serious, hayfever can trigger an asthma attack in a susceptible child. Hayfever rarely occurs before the age of five, and children tend to be worse affected during adolescence. Very often, these are children with an existing allergic tendency, who perhaps exchange a former allergic reaction, such as eczema, for hayfever (see Allergies). There may be an inherited disposition to allergies and / or hayfever, or it may be that weak digestion, poor diet or low general health has rendered the immune system and respiratory tract over-susceptible to pollen. Hayfever often occurs in children who have a tendency to chronic catarrh or frequent respiratory infections, as the mucous membranes are already irritated. It appears Read more […]

Common Herbal Remedies for Anxiety

Ayurveda, the Indian traditional system of medicine uses herbs and their preparations to treat various neuropsychiatric disorders. Numerous herbs have been used for centuries in folk and other traditional medicine to calm the mind and positively enhance mood. Herbal medicine which plays an important role in developing countries, are once again becoming popular throughout developing and developed countries. Study by Sparreboom et al. revealed that use of herbal medicine is increasing enormously in the Western world. In spite of the large number of animal studies evaluating the potential anxiolytic effects of plant extracts, very few controlled studies have been conducted in a clinical setup. The efficacy and safety of utilizing these natural drugs to treat anxiety, has only just begun to be exactly tested in clinical trials within the last 10 to 15 years. For instance, both Kava-kava (Piper methysticum) and St. John’s wort (Hypericum perforatum) showed beneficial effectiveness in double blind, randomized placebo controlled trials to treat anxiety and depression. Also, extracts of valerian, hops, lemon balm and passion flower preparations have been employed for the prevention and treatment of psychiatric disorders such Read more […]
