Ayurvedic medicine Ayurveda for short is one of the world's oldest holistic whole-body healing systems.
It was developed more than 3000 years ago in India.
It's based on the belief that health and wellness depend on a delicate balance between the mind body and spirit.
Its main goal is to promote good health not fight disease But treatments may be geared toward specific health problems.
The different dosage forms available under Ayurveda system are followingLIQUID DOSAGE FORMS
SOLID DOSAGE FORMS.
SEMI- SOLID DOSAGE
Ayurveda believe every person is made of five basic elements found in the universe space, air, fire, water, and earth.
These combine in the human body to form three life forces or energies, called doshas.
They control how your body works.
They are Vata dosha (space and air)
Pitta dosha (fire and water)
Kapha dosha (water and earth).
Vata DoshaThose who practice Ayurveda believe this is the most powerful of all three doshas.
It controls very basic body functions like how cells divide.
It also controls your mind, breathing, blood flow, heart function and ability to get rid of waste through your intestines.
If vata dosha is your main life force, you're thought to be more likely to develop conditions like anxiety, asthma, heart disease, skin problems, and rheumatoid arthritis.
Pitta DoshaThis energy controls your digestion, metabolism (how well you break down foods), and certain hormones that are linked to your appetite.
Things that can disrupt it are eating sour or spicy foods and spending too much time in the sun.
If it's your main life force, you're thought to be more likely to have disease, heart disease, high blood pressure, and infections.
Kapha DoshaThis life force controls muscle growth, body strength and stability, weight, and your immune system.
You can disrupt it by sleeping during the day, eating too many sweet foods, and eating or drinking things that contain too much salt or water.
If it's your main life energy, practitioners believe you may develop asthma and other breathing disorders, cancer, diabetes, nausea after eating, and obesity.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

generation to generation.
The written history has originated which was based on region, religion
and culture etc.

deals with the study of structural, physical, chemical, biochemical and
sensory characters of natural drugs of plant and animal origin.
It also includes a study of their history, distribution, cultivation, collection,
identification, preparation, evaluation, preservation, use and commerce.
At present pharmacognosy involves not only the crude drugs but also their
natural derivatives (pure compounds or constituents).

14. Extraction process
Extraction : It defined as the treatment of the plant or animal

dissolved and most of the inert matter remains undissolved.
The solvent used for extraction is known as “menstruum.”
And the inert insoluble material that remains after extraction is
called “marc”.

16. Solvent used in Extraction processes
Water
Water is a solvent for protein , colouring matter, gums, glycosides,
sugars, alkaloidal salts, enzymes, many organic acids and most of the
organic salts.
Waxes ,fats ,fixed oils and most alkaloids are insoluble in water.
Alcohol
Alcohol is solvent for alkaloids , glycosides, volatile oils and resins.
