Study Notes
Silymarine
- Silymarine is a choleretic and hepatoprotective agent that scavenges free radicals and exhibits antioxidant activity.
- It increases the production of natural antioxidant compounds, such as glutathione.
- Medically, it is used as a supportive treatment for chronic congestive heart failure, hypertension, and arteriosclerosis.
- It is also used to treat anxiety and insomnia.
Proanthocyanidins and Flavonoids
- Proanthocyanidins and flavonoids have a vasodilating effect, increasing coronary blood flow and exhibiting a positive inotropic effect.
- They also have antiarrhythmic properties.
- Adverse reactions may include an allergic response to plants of the Asteraceae family.
- Drug interactions may occur due to improved liver function, affecting the metabolism of certain medications.
Hops Strobile
- Hops strobile is the dried strobiles or inflorescences of the female plants of Humulus lupulus, belonging to the Cannabaceae family.
- The major constituents of hops strobile include bitter principles, bitter acids, condensed tannins, essential oil, and flavonoids.
- Medically, it is used as a sedative for treating restlessness and anxiety, as well as for insomnia and sleep disorders.
- It is also used to treat dyspepsia and lack of appetite, and is utilized in the manufacture of beer.
Mechanism of Hops Strobile
- The mechanism of action of hops strobile involves CNS depressant activity due to the bitter resins, which increase the activity of the GABA neurotransmitter, resulting in a calming effect.
Classification of Fruits
- Fruits can be classified into different types, including:
- Logume: Monocarpellary ovary that splits along both dorsal and ventral sutures.
- Dehiscent: The pericarp becomes dry and remains attached to the plant, splitting when ripe to release the enclosed seeds.
- Follicle: Monocarpellary ovary that splits by the inner suture only.
- Capsule: Multicarpellary (syncarpous) ovary that opens either by pores, valves, or lids.
- Achene: Monocarpellary ovary with a single seed, where the pericarp is free from the testa.
- Dry: Pericarp is hard and dry, and cannot be differentiated into epicarp, mesocarp, and endocarp.
- Indehiscent: The pericarp does not split even after ripening.
- Grain (Caryopsis): Monocarpellary ovary with a single seed, where the pericarp and testa are fused together.
- Nuts: Bi- or multicarpellary ovary with a single seed, where the pericarp is hard, woody, or leathery.
- Cypsela: Bicarpellary ovary with a single seed, where the pericarp and seed coat are free.
- Shizocarpic: Fruits develop from a bi-locular ovary, splitting into one-seeded, indehiscent parts called mericarps.
- Cremocarp: Fruit formed from a bicarpellary, bilocular inferior ovary, splitting into two one-seeded indehiscent mericarps attached with a carpophore.
- Drube: Pericarp is leathery, mesocarp is fleshy, and endocarp is hard and woody.
- Succulent: Pericarp or most of it is fleshy.
- Berry: Pericarp is fleshy, endocarp is neither hard nor lignified, and usually multi-seeded with embedded in the fleshy part.
- Aggregate: Developed from multicarpellary apocarpous (free carpels) ovary of a single flower (one receptacle).
- False: Formed when other parts of the flower take part in its formation.
- Composite (Multiple): Formed from the whole inflorescence (more than one flower) and not from a single flower.
Fennel and Anise
- Fennel is the dried ripe fruits of Foeniculum vulgare, belonging to the Apiaceae family.
- Anise is the dried fruits of Pimpinella anisum, also belonging to the Apiaceae family.
- The major constituents of fennel and anise include essential oils, flavonoids, proteins, and fixed oils.
- Medically, they are used as carminatives in dyspepsia and flatulence, as lactagogues, and as antispasmodics in mild inflammation of the upper respiratory tract.
- They are also used as expectorants in mild inflammation of the respiratory tract and as emmenagogues in dysmenorrhea.
Other Medicinal Plants
- Ammi visnaga is used externally in the treatment of skin disorders, such as psoriasis, vitiligo, and alopecia, and is administered in conjunction with long-wave UV radiation therapy.
- Xanthotoxin acts as a photosensitizing agent, stimulating melanogenesis and inducing repigmentation of the skin.
- It also reduces inflammation and cutaneous hyperproliferation in combination with long-wave UV radiation.
- Ammi majus is used internally as a condiment and to relieve dyspepsia, and is used externally to relieve rheumatic pain and arthritis.
- Capsicum is used to treat dyspepsia related to the biliary system, gall bladder disorders, and to support the improvement of liver function.
