Summary
Balsams, including benzoin and tolu balsam, are plant-derived resins historically used in medicine. Today, they are primarily used topically for skin conditions and in diaper ointments.
Area of Science:
- Pharmacognosy
- Dermatology
- Natural Products Chemistry
Background:
- Balsams are aromatic, resinous plant exudates with a long history of medicinal use.
- Key components include benzoic and cinnamic acids, contributing to their therapeutic properties.
Purpose of the Study:
- To review the historical and current applications of balsams in pharmacy.
- To highlight the relevance of balsams in contemporary dermatological treatments.
Main Methods:
- Literature review of historical texts and modern pharmaceutical journals.
- Analysis of balsam composition and traditional formulation types.
Main Results:
- Balsams have been utilized both orally and topically for centuries.
- Current primary applications are topical, in solutions, ointments, creams, and lotions.
- Common uses include diaper ointments and treatment of various skin disorders.
Conclusions:
- Balsams remain valuable in modern pharmacy, particularly for topical dermatological preparations.
- Pharmacists continue to compound formulations utilizing balsams for therapeutic purposes.

Aromatic Compounds: Overview
11.8K
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.

Seasoning of Wood
811
Seasoning of wood is a crucial process aimed at reducing and stabilizing the moisture content within the wood to prevent future shrinkage, structural damage, or aesthetic issues once the wood is used in construction. Wood naturally swells when it absorbs moisture and contracts as it dries.
Achieving equilibrium moisture content is the goal of seasoning; this is the point where the wood's moisture content stabilizes to align with the moisture levels of the surrounding environment. Proper...

Lumber
563
Lumber is derived from logs which are harvested, debarked, and processed into long pieces with a rectangular cross-section. The transformation of logs into lumber involves multiple steps, beginning with an automated saw that slices the log into slabs. These slabs are then transported via a conveyor belt to smaller saws, where they are cut into square-edged pieces of specific widths.
Initially, the surfaces of these lumber pieces are rough, and their dimensions may vary slightly from one end to...

Wood Surfacing
493
Wood surfacing is a critical finishing process designed to smoothen the wood surface, enhance its dimensional accuracy, and make handling safer. This process compensates for potential shrinkage during the seasoning phase by marginally increasing the wood dimensions before surfacing. It also helps correct some distortions that may occur as the wood dries.
The equipment used in the surfacing process is a plane equipped with rotating blades. This tool efficiently smoothens the wood surface and can...

Esters to Carboxylic Acids: Saponification
5.5K
Esters can be hydrolyzed to carboxylic acids under acidic or basic conditions. Base-promoted hydrolysis of esters is a nucleophilic acyl substitution reaction in which esters react with an aqueous base, followed by an acid to give carboxylic acids. This reaction is also known as saponification because it forms the basis for making soaps from fats.
The reaction requires a base in stoichiometric amounts, which participates in the reaction and is not regenerated later. So, the base acts as a...

One-Compartment Open Model for IV Bolus Administration: General Considerations
1.0K
The one-compartment model is a pharmacokinetic tool that models the body as a single, uniform compartment, facilitating the understanding of drug distribution and elimination. This model is particularly beneficial for intravenous (IV) bolus administration, where the drug rapidly circulates throughout the body.
The drug's presence in the body is defined by an equation representing the difference between the rates of drug entry and exit. Key parameters—elimination rate constant,...
