"Avicenna's Canon of Medicine." Introduction.Avicenna begins The Canon with a definition of the science of medicine: Medicine (tibb) is the science by which we learn the various states of the human body in health and when not in health, and the means by which health is likely to be lost, and when lost, is likely to be restored. In other words, medicine is the art whereby health is conserved and the art whereby it is restored after being lost. Avicenna insists that the human body cannot be restored to health unless the causes of both health and disease are determined. In categorising the causes, he states that a complete knowledge may be, and should be obtained of the causes and antecedents of a disease, provided, of course, such causes exist. Sometimes these causes are obvious to the senses but at other times they may defy direct observation. In such circumstances, causes and antecedents have to be carefully inferred from the signs and symptoms of the disease.
A Herbarium A Herbarium By Andrea Tarozzi, February 1996 English version revised by Edward Green Here the Belorussian version The most important part of every collected specimen is the flower, so the best seasons for picking up plants are spring and summer; but remember that certain species show their flowers in autumn or even winter, so do not neglect colder months for your excursions. Slippery Elm Botanical Name:Ulmus fulva, Ulmaceae Botanical synonyms: Ulmus rubra Common names: Slippery Elm, Red Elm Similar species: Ulmus effusa, Ulmus americana, Ulmus alata. Plant description: Slippery Elm is a medium to large deciduous tree from 6 to 24 meters in height, with rough irregular brownish bark on the main trunk that becomes whitish on the branches. The outer bark contains a thick,soft cambium layer,yellowish and very mucilaginous, lying over top a reddish-colored wood.

Ethnobotanists aim to document, describe and explain complex relationships between cultures and (uses of) plants, focusing primarily on how plants are used, managed and perceived across human societies. This includes use for food, clothing, currency, ritual, medicine, dye, construction, cosmetics and a lot more. Richard Evans Schultes, called the "father of ethnobotany", explained the discipline in this way:
"Avicenna" Abn Ali Al Hosain Ibn Abdallah Ibn Sina, or in Latin abbreviated to Avicenna. Arabian physician and philosopher, born at Kharmaithen, in the province of Bokhara, 980; died at Hamadan, in Northern Persia, 1037. The life of Avicenna is well documented in the book the "Life of Avicenna", which is based on his autobiography, written by his disciple Jorjani (Sorsanus), and which was published in the early Latin editions of his works. Avicenna's lived during a period of great political instability, which profoundly influenced his life.
at l'herbier: On the make // Botanical Herbarium Press There's no need to make a professional herbarium press if you're happy with your standard one. I wanted to end up with professionally mounted herbarium specimens, as you would find in a herbarium such as say, Kew, the Natural History Museum or the Linnean collections – as much for the art and beauty of the finished mount as for the potential to create various herbariums of locations associated with me and use the results for a series of related / further projects. Thus, I searched online to find a herbarium standard press, but could only find the traditional wooden ones for sale in the US; none in the UK. Too much money to ship one over, so what to do but make one. The process of doing so was as enlightening about the process of pressing and mounting herbarium specimens as it was a lesson in basic carpentry, as each stage of planning and making required specific measurements, materials and finishes. Thanks be to my artist / carpenter husband for helping me out on the technicalities.
Tree Species There are many different types of trees around the world. Some are very common and live in many different habitats. Below are four of the more widespread hardwoods and conifers of western Washington and Oregon with a little bit of information and pictures. Database Search To the best of our knowledge all the information contained herein is accurate and true. However we cannot guarantee that everyone will react positively to all edible plants or other plant uses. It is commonly known that many people suffer allergic reactions to conventional foods and products. Even amongst the more commonly eaten fruits, for example, there are plenty of instances where people react badly to them: Many people are allergic to strawberries and will come out in a rash if they eat them. Some people develop a rash if they touch the stems of parsnips.
Ethnobotany Education and Training Program Information Ethnobotany, the study of the human-plant physiological relationship, is typically only offered as an undergraduate major. Undergraduate students engage in field research and laboratory studies. Students looking to study ethnobotany at the graduate level might find some courses available as part of a degree program in a related field, such as botany or ecology. plant structure bi Seed Plant Overview: The plant body consists of two basic parts--- the shoot system and the root system Shoot system is above ground and includes organs such as leaves, buds, stems, flowers, and fruits The functions of the shoot system include photosynthesis, reproduction, storage, transport, and hormone production The root system is below ground and includes roots as well as modified stem structures such as tubers and rhizomes The functions of the root system include anchorage, absorption, storage, transport, and production of certain hormones Seed plants contain 2 types of vascular tissue (xylem & phloem) to help transport water, minerals, & food throughout the root & shoot systems Plant cells have several specialized structures including a central vacuole for storage, plastids for storage of pigments, and a thick cell wall of cellulose Plant cells are all box-shaped in appearance Meristems: Root Tip with Meristems

Living in Montana USA makes me appreciate the seasons more than ever. Although I was born here (so I have ancestral connection), I was raised in California, and mostly in San Diego!
Online Teaching Resources about Medicinal Plants and Ethnobotany + Affiliations Exploring plant-based medicines and ethnobotany (the scientific field that examines a culture’s knowledge, customs, and uses of plants) in the classroom is a timely and valuable way to engage students in science. People have used plants as medicines since at least the beginning of written history, with ancient Egyptian and Chinese texts describing medicinal uses of plants before 2500 BCE (Petrovska, 2012). The majority of the world’s people use medicinal plants for some of their medical needs, and the World Health Organization (WHO) recognizes plant-based medicine as an essential component of health care (WHO, 2002).The use of plant-based medicines has skyrocketed in the United States in the past few decades, increasing from 2.5% in 1990 to 12.1% in 1997 (Eisenberg et al., 1998). In 2012, nearly 5% of American children (Black et al., 2015) and 18% of adults (Clarke et al., 2015) used a non-vitamin, non-mineral natural supplement.
