In this ppt the viewer will able to know about Herbal Drug Preparation. An herb is a plant or plant part used for its scent, flavor, or therapeutic properties. Herbal medicines are one type of dietary supplement. They are sold as tablets, capsules, powders, teas, extracts, and fresh or dried plants. Dosage forms are the means by which drug molecules or plant parts are delivered to sites of action within the body. The routes for which herbal dosage forms may be administered include oral, rectal, topical, parenteral, respiratory, nasal, ophthalmic and otic. Categorization of finished herbal products into dosage forms will help to define specific protocols for quality control and stability testing. Herbal medicinal products may be defined as finished, labelled medicinal products that contain as active ingredients aerial or underground parts of plants, or other plant material, or combinations thereof, whether in the crude state or as plant preparations.

Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.

Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

2. Introduction
Herbal formulations is a dosage form consisting of one or more herbs or
processed herbs in particular quantities to provide specific nutritional,
cosmetic benefits and are meant to diagnose,treat,alleviate disease of human
beings or animals ,alter the structure of human beings or animals.
Herbal formulation contain a herbal substance or in combination with one or
more herbal substances to process like extraction,distillation,fractionation,
fermentation include powder.
Polyherbal formulations means the use of more than one herb in a therapeutic
preparation.
In Ayurveda multiple herbs in a particular ratio may be used in the treatment of
illness.

5. The syrup is made with equal proportion of the herbal infusion or decoction and
honey or unrefined sugar .
when making infusion or decoction for syrup ,it needs to be infused or simmered
for long time in order to optimize its medical action .
Infusion should be for 15 min and decoction for 30 min.
Then soaked herb was pressed through the strainer or sieve to remove as
much as liquid as possible .
A small amount of tincture can be added to increase effectiveness .
The syrup may also be made with tinctures instead of infusion or
decoctions.
500 gm of honey or unrefined sugar is combined with 250 ml 0f water .It
is Gently heated until all the sugar or honey has dissolved and the
mixture has thickened
Once cooled ,one part of the tincture, mixture of tincture is stirred into
three parts of the syrup and stored.
6. Advantages of Herbal syrup
Mask bad taste of
drugs
Soothing effect
on irritated
tissues due to
viscous nature
Used for
pediatric
formulations
7. Methods for the Preparation of syrup
Solution with heating
Agitation without
heating
Used when constituent is heat
stable and nonvolatile
The sucrose is added to the
purified water and heated until
solution is formed
Ten it is strained and sufficient
purified water is added to make
up the volume
Used in case of heat labile and
volatile constituents.
Glass–lined tanks with mechanical
agitators , for dissolving sucrose are
used for making syrups in large
quantities.
8. Preservations and storage
1
• Syrups should be made in quantities that can be consumed within few
months in those cases where preservation is done at low temperature
2
• Syrups may contain preservatives like,glycerin,methyl paraben ,benzoic acid
and sodium benzoate
3
• Any simple syrup can be preserved be preserved by substituting glycerin for
a certain portion of syrup
4
• They can be stored in dark glass bottles with cork tops in a cool place for
upto 6 months
5
• They should be stored at temperature not exceeding 30 ° C
6
• Dosage -1-2 teaspoonful, Three times a day
9. Example of some syrup preparations

powdered
ingredients
and excipients
Convert into
granules
compressionCoatingEvaluation
14. Weighing of ingredients
If crude drugs are used they must first be ground into fine powder and
passed through a no.100 mesh sieve.
Mixing
All the medicaments and excipients are mixed uniformly so that uniform
tablets can be manufactured. The mixing of ingredients should be done
in an ascending order of their weight.
Converting the mixed
into granules
1) Wet granulation
2) Dry granulation
3) Granulation by preliminary compression
15. The dried granules obtained above are compressed into tablets by using a tablet
punching machine.
The compression is achieved by filling the required quantity of granules into die
and then compressing them between the lower punch and upper punch .
Coating of a tablet is required-
1) To mask the unpleasant taste and odour
2) To improve the appearance of the tablet
3) To protect the medicaments from atmospheric effects,
4) To control the site of action of drugs and to produce sustained release of the
product
16. Coating of tablet required to mask the unpleasant taste and odour,
improve the appearance of the tablets
to protects the medicaments from the atmospheric effects,
to control the site of action of drugs and
produce sustained release of the products.
The coating is generally carried out either by using pan or press coating.
Pan coating is used for -
Sugar
coating
Enteric
coating
Film
coating
17. Novel Dosage forms
Now a days significant attention has bees concentrated on the development of
novel drug delivery system (NDDS) for herbal drugs.
Conventional dosage forms are not capable to satisfy the requirements of
holding the drug component at a distinct rate all through the period of holding the
drug component at a distinct rate all through the period of treatment and are not
target specific.
In phyto formulation research ,development of a nano-sized dosage forms has
number of advantages for herbal drugs, like –
1) Improvement of solubility and bioavailability
2) Increase stability
3) Improving distribution of drug in tissues
4) Sustained delivery
5) Protection from physical degradations
18. Phytosome
The word Phyto means plant and some means cell like .
Phytosomes are small cell like structure.
A phytosome is a complex made up of natural active ingredients or drug and a
phospholipid mostly lecithin.
Phytosome include herbal drug which is loaded in vesicles and is available in the
nano form.
The phytosome provide a coating around the active constituent of drug and due to
this main constituent of herbal extract remains safe from degradation by digestive
secretion and bacteria.
Phytosome is effectively absorbed from water loving environment of the cell
membrane and finally reaching to the blood circulation.
It can be used in the treatment of various fatal disease without denaturating the
active phyto compounds and also enhances bioavailability.
19. 1
• Phytosome prepared by adding accurate amount of phospholipids i.e
soya lecithin with herbal extract in an aprotic solvent
2
• Soya lecithin contain phosphatidylcholine which is having a double
function
3
• Phosphatidyl part is lipophilic in nature and choline part is
hydrophilic in nature
4
• The choline part is attached with hydrophilic constituent ,where as
phosphatidyl part is attached with lipid soluble compound
5
• It is result in the formation of lipid complex with better stability and
bioavailability
