Tyrosine can help with the following
Depression
Particular precursors such as tyrosine, which increases dopamine and noradrenaline, show beneficial results in the treatment of mild depression.
Hives
One older study reported that L-tyrosine (200mg), vitamin B6 (2.5mg) and niacinamide (10mg) when given in combination for the treatment of hay fever, hives, allergic headaches and poison oak dermatitis produced significant symptomatic relief when 1-3 tablets were taken four times per day in milder cases and up to 6 tablets 4-6 times per day in more severe cases.
In some cases characterized by more chronic disorders, such as chronic sinusitis, a worsening of symptoms often occurred during the first few days of treatment. This study found that treatment with each of the nutrients individually, or with any two in combination, was ineffective. [Widmann RR, Keye JD Epinephrine precursors an control of allergy.

Glossary
Amino Acid
An organic acid containing nitrogen chemical building blocks that aid in the production of protein in the body. Eight of the twenty-two known amino acids are considered "essential," and must be obtained from dietary sources because the body can not synthesize them.
Melanin
A dark pigment produced in the skin. Dark-skinned individuals produce more melanin, and melanin production increases in response to sunlight, causing the skin to become darker.
Anxiety
Apprehension of danger, or dread, accompanied by nervous restlessness, tension, increased heart rate, and shortness of breath unrelated to a clearly identifiable stimulus.
