Astragalus sarcocolla is a species of plant in the legume family, Fabaceae. It is a member of the genus Astragalus, which includes a large number of species commonly known as milkvetches. Astragalus species are often characterized by their distinctive flowers and growth habits, and they can be found in various habitats around the world.
Asafoetida, also known as "hing," is a potent spice derived from the resin of the Ferula plant, mainly Ferula assa-foetida. It is native to the regions of Iran and Afghanistan and is widely used in Indian cuisine, particularly in vegetarian dishes, due to its strong flavor and aroma. The spice has a pungent, garlic-like smell when raw, but it becomes mellow and flavorful when cooked.
Apiol, also known as parsley seed oil or 4-allyl-1,2-dimethoxybenzene, is a chemical compound primarily derived from the seeds of plants in the Apiaceae family, particularly from parsley (Petroselinum crispum). It is known for its strong aroma and is often used in traditional herbal medicine, aromatherapy, and as a flavoring agent in food products.
Ammoniacum, also known as ammoniac, is a natural gum resin that is harvested from the sap of specific species of plants, particularly those in the genus *Ferula*, which belong to the umbellifer family. The most commonly used species for this purpose is *Ferula assa-foetida*, also known as asafetida or devil's dung. Ammoniacum is typically found in regions like Persia and Afghanistan.
Agarwood, also known as Oud or Aoud, is a highly valued and fragrant wood that is derived from the Aquilaria tree, particularly from species such as Aquilaria malaccensis. When the tree gets infected with a specific type of mold (Fusarium species), it responds by producing a dark, aromatic resin as a defense mechanism. This resin is what gives agarwood its distinctive scent and makes it so sought after.
Resin sculptures are artworks created using synthetic resin, a versatile material that can be molded, cast, and manipulated in various ways. Resin is typically composed of a combination of polymers that can be formulated to achieve different properties, allowing artists to create intricate designs, vibrant colors, and unique finishes.
Natural gums are complex polysaccharides derived from plants, trees, or certain microorganisms. They are primarily composed of sugars and can be found in various parts of plants, including the exudates from tree bark, the seeds, and the cells of some marine algae. Natural gums have a wide range of applications in various industries due to their thickening, gelling, stabilizing, and emulsifying properties.
Fossil resins, commonly known as amber, are natural polymers that have undergone fossilization over millions of years. They originate from the resin secreted by various trees, particularly coniferous species, which is a sticky substance produced as a defense mechanism against pests or disease. Over time, the resin can become buried under sediment, and through processes such as heat and pressure, it hardens and transforms into a solid material.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
