3. • Antiabsorptive and hydragogue laxatives
• - The "drastic" effects can be attributed to their anthranoid content.
- It is designed for short-term use (why ? 1. rebound constipation and melanosis coli )
and should never be used for extended periods of time.
• Mechanism of action:
• Anthranoids intestinal motility and the reabsorption of electrolytes (fluid from the
colon) the vol. of the intestinal contents and the intestinal filling pressure
induces propulsive contractions.

14. Gastrointestinal infections and diarrhea
The most common causes of acute and chronic diarrhea are
1- Infectious agents. 2- Drugs or toxins 3- Food additives 4- idiopathic diarrhea
5- Inflammatory bowel diseases 6- Malabsorption
Natural products and conservative measures in diarrhea.
1- Tannin-containing herbs act as astringents will also gently control diarrhea without risk of
aggravating the infection by reducing intestinal motility. They also reduce mucosal damage.
2- polysaccharides (e.g. pectin and starch)
Rice starch glucose (by enzymatic hydrolysis in GIT) enhance absorption of water and Na+
(by co-transport of sugar and Na+).
Eat more foods containing starch. Starchy foods are easily digested during diarrhea. Examples
are rice and mashed potatoes.
3- Opiates reduce GIT motility
4- Normal conservative measures such as adequate fluid and electrolyte intake should also be
implemented.
15. - Restoring water and electrolyte balance in cases of severe diarrhea
The world health organization formula:
Sodium chloride 3.5 g
Sodium bicarbonate 2.5 g
Potassium chloride 1.5 g
Glucose 20.0 g
1 liter of water
Oral rehydration solution (ORS) for treatment of diarrhea relies on enhancement of
small intestinal sodium and fluid absorption to correct dehydration.

Hemorrhoids
Hemorrhoids, also called piles, are vascular structures in the anal canal. They become a disease
when swollen or inflamed
Hemorrhoids are aggravated by pelvic congestion (e.g. constipation and pregnancy). Some
degree of loss of elasticity of the anal sphincter may play a role. Lifting heavy weights may
aggravate the condition.

23. Diseases of the liver
Liver is one of the most important organs of the digestive system. It is the principal organ of
metabolism of carbohydrates, proteins, fats and bile; the main organ of detoxification of harmful
foreign substance e.g. most chemicals numerous therapeutic drugs, toxic substances and
environmental pollutants.
Diseases of liver and biliary tract
As the liver is closely associated with the gall-bladder, problems of these organs are usually
considered in association.
1- choleretic action (stimulating the production of bile, and thus working directly on the liver
itself).
2- cholagogue action (increasing the release of bile from the gall bladder).
24.
25. Hepatitis (inflammation of the liver): Long term hepatitis may lead to cirrhosis (fibrosis)
and death.
1- Certain viral infection (viruses A, B, C – viral hepatitis).
2- Parasitic infections (e.g. bilharziasis and amebic desentery).
3- Excessive inhalation of chlorinated hydrocarbons, (e.g. DDT, CHCl3 and CCl4).
4- Ingestion of industrial pollutants (radioactive material), contaminated food (e.g. aflatoxin or
peroxides in oxidized edible oil), much alcohol and poor nutrition, Medication with antibiotics,
chemotherapeutic agents and possibly plant materials such as those contains pyrrolizidine
alkaloids.
Symptoms
1- Fever often accompanied by vomiting. 2- Pain around the liver, Nausea, anorexia, impairment
of fat digestion 3- Fatigue 4- Alcoholics can not tolerate alcohol.
5- jaundiced skin and dark urine (yellow discoloration of the skin or sclerae by bilirubin, when its
serum concentration exceeds 2 – 3 mg/100ml).
6- High levels of SGPT and SGOT enzymes, which are elevated in acute hepatitis.
26. Biochemical tests:
1. Blood glucose level falls leading to a fatal hypoglycemia.
2. Blood urea falls and ammonia? level rises.
3. Bilirubin accumulates in blood and jaundice develops.
4. Blood clotting is impaired by a fall in prothrombin and fibrinogen.
5. A fall in overall plasma proteins leading to decrease in osmotic pressure of plasma proteins
and this may result in edema.
7. Reduction of fat absorption due to decrease of bile salts.
Immunological tests:
- Hepatitis markers (in viral hepatitis).
- Antinuclear factor and smooth muscle antibodies " in chronic active hepatitis".
- Antimitochondrial antibodies (in biliary cirrhosis).
- alpha-fetoprotein (afp) (in liver cancer).
27. 1- Fatty liver: Excessive lipid in parenchyma cells .
2- Poor liver function
3- Acute viral hepatitis: the hepatitis A, B and C viruses.
4- Chronic viral hepatitis: usually results from infection with hepatitis B or C.
5- Cirrhosis of the liver: widespread death of liver cells, which can result from many causes but is
most commonly due to alcohol abuse (Europe ) Hepaitis C (Egypt) and B is accompanied and
followed by progressive fibrosis and distortion of liver architecture.
Treatment is based on the following:
- Hepatoprotective and hepatic trophorestorative herbs, Principal herbs include silybum,
artichoke and dandelion root, schisandra is particularly useful since it also enhances the
detoxifying capacity of the liver.
- Most of the hepatoprotective herbs listed above have a gentle choleretic activity
- Cholerctic herbs to boost liver function are particularly indicated if digestive symptoms are
predominant. They will also boost detoxification by the bile and therefore can be valuable in
conditions such as psoriasis and cancer.
- Strongly choleretic herbs include hydrastis, barberry, chelidonium and bitter herbs. These
strongly choleretic herbs will cause nausea and irritability in a patient who has some history of
liver damage ?.
28. - Antiviral agents, which for hepatitis include Hypericum perforatum (St John's wort), phyllanthus
and thuja.
- Immune-enhancing herbs, especially Nigella sativa, echinacea and picrorrhiza. but also
consider astragalus for any chronic infection.

hepatic stressors and disease. ex. Silybum marianum (milk thistle), cynara (artichoke and
schisandra.
Indications for hepatics: - Viral and other hepatitis.
- Adverse effects of alcohol and excess fat consumption.
- Exposure to industrial pollutants. - In anticipation with the powerful medications.
- Cirrhosis and other chronic liver diseases.
