Question: What are the therapeutic and standard purposes that horses are used for?
About the article "Equestrianism", section "Overview of equestrian activities".

Candidate passages:
The Therapeutic Goods Administration (TGA) is the regulatory body for therapeutic goods (including medicines, medical devices, gene technology, and blood products) in Australia.
It is a Division of the Australian Department of Health and Ageing established under the "Therapeutic Goods Act 1989 (Cth)".
The TGA is responsible for conducting assessment and monitoring activities to ensure that therapeutic goods available in Australia are of an acceptable standard and that access to therapeutic advances is in a timely manner. 
Horses are trained and ridden for practical working purposes such as in police work or for controlling herd animals on a ranch.
They are also used in competitive sports including, but not limited to, dressage, endurance riding, eventing, reining, show jumping, tent pegging, vaulting, polo, horse racing, driving, and rodeo.
(See additional equestrian sports listed later in this article for more examples.)
Some popular forms of competition are grouped together at horse shows, where horses perform in a wide variety of disciplines.
Horses (and other equids such as mules and donkeys) are used for non-competitive recreational riding such as fox hunting, trail riding or hacking.
There is public access to horse trails in almost every part of the world; many parks, ranches, and public stables offer both guided and independent riding.
Horses are also used for therapeutic purposes, both in specialized paraequestrian competition as well as non-competitive riding to improve human health and emotional development.
Horses are also driven in harness racing, at horse shows and in other types of exhibition, historical reenactment or ceremony, often pulling carriages.
In some parts of the world, they are still used for practical purposes such as farming.
Horses continue to be used in public service: in traditional ceremonies (parades, funerals), police and volunteer mounted patrols, and for mounted search and rescue.
The genus "Agaricus" includes some species that are cultivated commercially throughout the world.
The common "button mushroom", "Agaricus bisporus", is the most widely cultivated edible mushroom.
"Agaricus blazei" is a well-known medicinal mushroom used for a number of therapeutic and medicinal purposes.
Several species are poisonous, such as some "Lepiota" and "Chlorophyllum" species. 
People of all ages with physical and mental disabilities obtain beneficial results from association with horses.
Therapeutic riding is used to mentally and physically stimulate disabled persons and help them improve their lives through improved balance and coordination, increased self-confidence, and a greater feeling of freedom and independence.
The benefits of equestrian activity for people with disabilities has also been recognized with the addition of equestrian events to the Paralympic Games and recognition of para-equestrian events by the International Federation for Equestrian Sports (FEI).
Hippotherapy and therapeutic horseback riding are names for different physical, occupational, and speech therapy treatment strategies that utilize equine movement.
In hippotherapy, a therapist uses the horse's movement to improve their patient's cognitive, coordination, balance, and fine motor skills, whereas therapeutic horseback riding uses specific riding skills.
Horses also provide psychological benefits to people whether they actually ride or not.
"Equine-assisted" or "equine-facilitated" therapy is a form of experiential psychotherapy that uses horses as companion animals to assist people with mental illness, including anxiety disorders, psychotic disorders, mood disorders, behavioral difficulties, and those who are going through major life changes.
There are also experimental programs using horses in prison settings.
Exposure to horses appears to improve the behavior of inmates and help reduce recidivism when they leave. 
Therapeutic foods are foods designed for specific, usually nutritional, therapeutic purposes as a form of dietary supplement.
The primary examples of therapeutic foods are used for emergency feeding of malnourished children or to supplement the diets of persons with special nutrition requirements, such as the elderly.
Therapeutic foods are usually made of a mixture of protein, carbohydrate, lipid and vitamins and minerals.
Therapeutic foods are usually produced by grinding all ingredients together and mixing them.
“The mixing process allows for the protein and carbohydrate components of the food to be embedded in the lipid matrix.
The size of the particles in the mixture has to be less than 200 µm for the mixture to maintain its consistency.
Using this method, the therapeutic food is produced and packaged without using water, which would eliminate the issue of spoilage.
Some therapeutic foods require the addition of water before administering, while others can be consumed as-is.
Therapeutic foods are designed and manufactured to ensure that they are ready to eat straight from the packaging.
Those foods resist bacterial contamination and require no cooking.
The World Health Organization's standards for the treatment of malnutrition in children specify the use of two formulas during initial treatment, F-75 and F-100.
These formulas contain a mixture of powdered milk, sugar, and other ingredients designed to provide an easily absorbed mix of carbohydrates and essential micronutrients.
They are generally provided as powdered mixes which are reconstituted with water.
The WHO recommends the use of these formulas, with the gradual introduction of other foods, until the child approaches a normal weight.
The standard treatment of childhood malnutrition is administered in two phases.
Phase one usually deals with children who are severely malnourished and very ill as a result.
The therapy used in this phase is F-75, a milk-based liquid food containing modest amounts of energy and protein (75 kcal/100 mL and 0.9 g protein/100 mL) and the administration of parenteral antibiotics.
When an improvement in the child’s appetite and clinical condition is observed, the child is entered into phase two of the treatment.
This phase uses F-100.
F-100 is a “specially formulated, high-energy, high-protein (100 kcal/100 mL, 2.9 g protein/100 mL) milk-based liquid food”.
The child is in phase two until he/she is no longer wasted z score (WHZ) 2.
Phase two starts while the child is at the hospital but is usually completed after the child goes home.
The parent is then responsible for feeding the child a flour supplement made of cereal and legumes as a replacement for the milk-based foods used in phases one and two.
